Original Post In modern software development, monorepos have become a standard solution for managing complexity. Housing multiple applications and libraries in a single repository offers undeniable advantages, though it's a strategy that must be weighed carefully. (If you're still debating between a monorepo and a multi-repo, I've explored that decision in detail in my article Repository Architecture: Exploring Monorepo, Multi-repo, and Beyond). Once you commit to a monorepo, it brings a headache that grows over time: speed. As the project expands, build, test, and linting times skyrocket. Tasks that once took seconds now take minutes (or hours). This is where modern build systems come into play. Today, two titans dominate this conversation: Nx and Turborepo. I've helped multiple teams sca…  ( 9 min )

Progressive Web Apps: Building Offline-First UIs – Never Lose Your Users Again! Ever been browsing a website on your phone, only to have the page die the second you lose signal? Frustrating, right? In today's world, users expect a smooth, reliable experience, even when their internet connection is spotty. That's where Progressive Web Apps (PWAs) come in, and their ability to build offline-first UIs is a game-changer. Imagine you're running an e-commerce site. A user is browsing your products, adding items to their cart, and about to checkout. BAM! Lost connection. All that effort, gone. They're likely to abandon their cart and maybe even your site forever. Building offline-first solves this problem and offers huge benefits: Improved User Experience: Users can access content and functio…  ( 8 min )

Context There are numerous situations where we need an independent and isolated DB. For example, developers want to test their code or the Ops team needs to run upgrade tests and etc. The common approach is restoring a snapshot. However, it can become expensive and inefficient over time for repetitive tasks. The "AWS Aurora Clone" becomes handy in this situation, where it provides a more efficient solution in terms of operation and cost. The Aurora clone uses copy-on-write protocol and works in a way that it shares the same volume between the source and clone cluster(s), but the updates are only visible to the respective cluster. I have shared, how the Aurora clone has been integrated into our GH actions to enable developers, spin up an independent and isolated Aurora RDS cluster, which …  ( 7 min )

Thirty days. No funding. No team. Just one laptop, too much coffee, and a clear mission: fix the broken hiring process. It started with frustration. Too slow. Too opaque. Too fragmented. I wanted to build something that felt human, fast, and transparent. So I set a challenge: Build the first working version in 30 days. The goal wasn’t to build everything. I wrote one question on my whiteboard: “What is the minimum version that delivers real value?” That became the filter for every decision. I cut out everything that didn’t directly help candidates or companies connect: no fancy dashboards no payment system no AI fluff (yet) Just jobs, profiles, filters — and the first mentors. The first milestone wasn’t “launch.” I built: Public candidate profiles Vacancy feed Dashboard for tracking Simple AI evaluation (keywords + relevance) Mentor cards and onboarding Telegram notifications When I deployed the first version, I had exactly 0 users. Momentum started. To move fast, I had to say “no” a lot. Company accounts? → later. Analytics dashboard? → later. Subscriptions? → later. AI matching? → partially mocked. If a feature didn’t help validate the core value — it waited. That’s how I shipped the alpha on time. The first 10 users taught me more than any product book. They didn’t care about “AI.” One message stuck with me: “For the first time, I actually see who posted the job.” That’s when I realized — transparency is the feature. Constraints are your best friend. Launch ugly. Talk to real people. Ship > plan. Now SkillHunt has: 15+ registered users Real vacancies First mentors onboard AI evaluation prototype A public alpha live at skillhunt.pro The mission remains the same: Make hiring transparent, fast, and human. It’s still early — but this is just the start. Building SkillHunt alone was intense — but deeply rewarding. If you’re building something — start small, ship fast, and listen hard.

The Day GitHub Copilot Changed How We Code When GitHub Copilot rolled out broadly in 2023–2024, the reaction was excitement. Faster coding Fewer bugs Less time searching StackOverflow A personal assistant inside your IDE Developers didn’t just gain speed — they gained relief. But something subtle followed. Junior developers stopped learning how to reason about problems. Senior developers began to approve code instead of designing it. Debugging turned into prompt tweaking. Understanding turned into confirmation bias. No one complained, because everything looked efficient. But beneath the surface, a quiet shift was happening. If AI writes the code, what does the developer create? This isn’t a productivity debate. It’s a purpose debate. In the 1960s, researcher John B. Calhoun…  ( 7 min )

When building UI, we often rely on icons or visual cues that don’t include visible text. While that might look clean, it can leave screen reader users guessing. aria-labelledby is one of the techniques we can use to give clear context to assistive technologies. aria-labelledby? aria-labelledby lets you reference visible text elsewhere in the DOM to create an accessible name for an element. It basically tells assistive technology: “Use this other element’s text to label me.” It’s commonly used when the text that explains an element is located outside the element itself.

File watching seems simple on the surface: "tell me when a file changes" But the reality is three completely different APIs with three fundamentally different philosophies about how computers should monitor file systems. I recently spent weeks building FSWatcher, a cross-platform file watcher in Go, and the journey taught me that understanding file watching means understanding how each operating system approaches the problems differently. Apple's philosophy is to monitor directory trees, rather than individual files. // You say: "watch /Users/me/fswatcher" // macOS says: "OK, I'll tell you when ANYTHING in that tree changes" Pros Low CPU usage Efficient for large directories Event-driven (no polling) Cons Gives you directory-level info, not file-level Can flood you with redundant events …  ( 8 min )

In today's digital world, data plays a crucial role in guiding business decisions. However, much of this valuable data is often locked within PDF documents, especially in the form of complex tables found in financial reports, contracts, invoices, and statistical data. Manually extracting data from these tables can be time-consuming, error-prone, and inefficient. Simple copy-pasting or text parsing often disrupts the structure of the tables, making it difficult to work with the data in a useful way. Efficiently extracting table data from PDFs and converting it into more accessible formats—like text files (TXT) or CSV—has long been a challenge for developers, data analysts, and project managers. In this article, we’ll take a closer look at the technical challenges involved in PDF table extra…  ( 9 min )

In the fast-moving world of software development, developers constantly deal with new frameworks, distributed systems, and microservices that make applications more powerful—but also more fragile. Even when individual components work perfectly, the moment they interact, unexpected issues can arise. That’s why end-to-end testing has become an essential part of modern development. It ensures that the application behaves correctly from the user’s perspective, validating entire workflows instead of isolated parts. End-to-end (E2E) testing verifies that all layers of an application—from the user interface to the backend, database, and external integrations—work together as intended. Unlike unit or integration testing, which focus on specific modules, E2E testing replicates real user scenarios. …  ( 7 min )

Setting the Stage Ever wondered why the features your favorite product promises often take longer than planned? Or why it sometimes feels like engineers deliver more promises than features? Considering how disappointing it feels, experiencing both sides of that letdown has taught me how crucial it is to deliver on time and with high quality. For frontend engineers, a core metric of their efficiency in replicating designs is how it looks on laptops, tablets, mobile devices, and large monitors: a phenomenon known as responsiveness. To achieve this, we define breakpoints: width thresholds that tell our layouts when to adapt. Here's the catch, though: during implementation of a design, browser debugging tools don’t show which breakpoint is currently active. Developers have to cross-check win…  ( 9 min )

I've been working with Node.js and its ecosystem. Over the past few months, I've switched to Go and I'm getting huge enjoyment from its approach — on one hand, simplicity and no syntactic sugar (you can get diabetes from all the sugar in JS, it's too sweet🙃), on the other hand, incredible capabilities and a greater sense of being "close to hardware." I decided to document my learning notes in an open repo AlgoDSgo — specifically, implementations of classic algorithms in Go. This isn't production code, but educational examples with comments and Big O complexity analysis. Sure, there are hundreds of similar repos... so what's the value in opening another one? 👇 Classic solutions to classic CS problems, without over-engineering or language-specific optimizations, for clear understanding of the algorithm. Meaningful semantic naming Aiming for simple and idiomatic Go code Breakdowns and diagrams right in the comments Search algorithms: Binary, Linear, Jump, BFS, DFS Sorting algorithms: Bubble, Selection, Insertion, Merge, Quick, Quick In-Place, Heap LeetCode problems: Two Sum #1, Merge Sorted Array #88, Valid Palindrome #125 Interview exercises: Reverse String, Remove Duplicates, Remove Whitespaces, Longest Word I'm planning to expand it by adding data structures and more LeetCode problems.

A hands-on guide to architecting multi-agent AI systems in Python instead of just writing prompts. Stop being a user, start being a builder. Alright, let's have a real talk, dev to dev. The term "Prompt Engineering" is starting to feel like "Webmaster" did in the early 2000s. It was a useful descriptor for a brief, transitional moment, but it fundamentally misunderstands the real, durable skill that’s emerging. We've all seen the flood of "ultimate prompt cheat sheets" and CO-STAR frameworks. They’re fine. They teach you how to ask a question a little better.

Welcome to "WTF is this," the daily blog series where we dive into the weird and wonderful world of emerging tech trends. Today, we're tackling a term that sounds like it was plucked straight from a sci-fi novel: chaos engineering. Because, you know, what's more exciting than intentionally causing chaos? So, what is chaos engineering? In simple terms, chaos engineering is the practice of intentionally introducing faults or failures into a system to test its resilience and ability to recover. Think of it like a firefighter setting small, controlled fires to test the fire department's response time and strategy. By simulating real-world failures, chaos engineers can identify potential weaknesses and improve the overall reliability of a system. But why is chaos engineering trending now? Well,…  ( 10 min )

AI is rewriting how software is built, not by replacing engineers but by redefining how teams think, plan, and deliver. The hardest part isn’t the technology, it’s the mindset shift required to make it actually work. After more than 15 years leading large-scale transformation programs across industries, continents, and technology waves, one lesson remains constant: every time a new capability arrives, we rush to adopt it before truly understanding how it fits our operating model. Whether it was cloud, DevOps, or now AI, the pattern repeats, organizations underestimate the cultural, architectural, and process redesign required to make new technology sustainable. When teams dive in without structured learning or disciplined experimentation, the result is inefficiency disguised as innovation.…  ( 9 min )

ServiceNow recently announced the end-of-life (EOL) for Lightstep, now known as Cloud Observability. Support will officially end on March 1, 2026, or at the end of your contract, and ServiceNow has confirmed there will be no direct replacement or migration path. This news can be disruptive for engineering teams who rely on Lightstep for critical observability. The announcement highlights a significant risk in relying on proprietary, closed-source tools for essential infrastructure. At SigNoz we believe critical infra shouldn’t hinge on a vendor’s roadmap. Observability is too critical a piece to leave to such risks. With open source, you always have an escape hatch. If you're now searching for a stable, future-proof alternative to Lightstep, you're in the right place. This guide will walk …  ( 15 min )

As organizations adopt cloud-native architectures like microservices and Kubernetes, they face an explosion of telemetry data. This data is essential for understanding system health, but it also brings significant challenges: soaring costs, tool fragmentation, and persistent alert fatigue for on-call engineers. Choosing the right observability platform is critical to managing this complexity. In the observability space, Datadog and Chronosphere are two popular solutions. Datadog is the established, all-in-one market leader, known for its broad feature set and ease of use.

“Five seconds.” That’s how long it took for everything to go wrong. Our team had just launched a promising app for event updates. We’d built a clean interface, solid backend, and smooth UX — or so we thought. But during the launch event, users began missing critical notifications. Updates were delayed by just five seconds. Sounds small, right? But in a world of instant expectations, five seconds is an eternity. That experience taught us one key truth: 👉 If your app isn’t real-time, it’s already behind. 🧠 Why Real-Time Notifications Matter Let’s face it — users today live in a fast-feedback world. Whether it’s a stock alert, chat message, food delivery update, or breaking news, people want to know now, not later. In modern app development, real-time notifications are no longer a luxury; t…  ( 8 min )

Datadog and Sumo Logic, both offer powerful tools to monitor applications. While they often appear in the same conversations, they were built with different core philosophies that shape their features, costs, and the day-to-day experience for engineers. Datadog is widely recognized as a market leader in infrastructure and application performance monitoring (APM). Sumo Logic, conversely, established its roots in log management and security analytics, positioning itself as a converged platform for both observability and security operations. This article provides a definitive, deep-dive comparison of Sumo Logic vs. Datadog. We'll go beyond marketing features to explore the technical details that matter most during implementation and incident response, from data path control to agent overhead.…  ( 13 min )

TL;DR: When to Choose Each Choose Datadog if: You need a managed (SaaS) platform for full-stack observability (metrics, traces, logs). Your team values speed, minimal setup, and a polished UI, and you have the budget for a per-use subscription. Choose Zabbix if: Your primary need is on-premise infrastructure and network monitoring. You prioritize zero licensing cost and total data control, and your team has the expertise to install, manage, and scale a self-hosted solution. Consider SigNoz if: You want the all-in-one (metrics, traces, logs) experience of Datadog but with the open-source, self-hosted flexibility. You're looking for a cost-effective, OpenTelemetry-native alternative without Datadog's high cost or Zabbix's lack of native APM. Teams looking for a monitoring solution face a key…  ( 13 min )

TL;DR: Too heavy for small setups or homelabs: pick a lighter self-hosted tool like Netdata, LibreNMS, or Checkmk. Don’t want to run and patch Zabbix yourself: go for a managed/commercial option like Datadog or PRTG Network Monitor. Need all-in-one observability for Kubernetes/microservices (APM + logs + metrics): use SigNoz or build Prometheus + Grafana. Zabbix is a veteran in the IT monitoring world. It's open-source, powerful, and exceptionally good at deep infrastructure and network monitoring. For many organizations, it's a reliable workhorse for tracking server health, network devices via SNMP, and service availability. But it's not a one-size-fits-all solution. As infrastructures evolve, many teams find themselves looking for an alternative. The "best" alternative depends entirely o…  ( 14 min )

Nova Twins kicked off NPR’s Tiny Desk with a mega-distorted bass line, relentless hip-hop beats and raspy yowls. London duo Amy Love and Georgia South didn’t ease in—“Cleopatra” tells haters to kick rocks, “Monsters” is a fierce shadow-self showdown, and between songs they duck under the desk to tweak their spaceship-sized pedalboards (they proudly admit they’re “massive pedal nerds”). They even strap on a Harp Blaster mic for “Hummingbird,” giving it supernatural vibes, then crank everything up for the heavy-rock finale “Choose Your Fighter.” It’s a bass-heavy, boundary-smashing set that flips the “nice, polite girls” script on its head.

TL;DR: Choose Datadog if: You need a powerful, all-in-one SaaS platform, value a polished user experience, and require the broadest range of (1,000+) turnkey integrations. It "just works" out of the box, but you should budget carefully for its per-host and per-event pricing, which can get expensive at scale. Choose Logz.io if: Your team is already familiar with open-source tools like OpenSearch (ELK), Prometheus, and Jaeger, and you want a managed version without the maintenance overhead. Its consumption-based pricing is more predictable for logging, and it offers strong tools for cost control. Consider SigNoz if: You are building on OpenTelemetry and want a truly OTel-native platform. This avoids vendor lock-in and gives you the choice of a transparent cloud offering or a self-hosted comm…  ( 11 min )

There’s an old saying I paraphrased in this by now ancient tweet[sic]: “Friends don’t let friends build their own {CRYPTO, SYNC, DATABASE}.” — @janl on September 24th, 2014 What do I mean by that?

What is OOP? Think of OOP like organizing things in your life. OOP is how you organize your code (using objects). Each object has: Properties (data) → things it has Methods (functions) → things it can do Example: A Car object "Has: color, brand, speed" "Can do: start(), stop(), accelerate()" So, instead of having a messy program with all logic mixed together, OOP groups related data and behavior inside objects — making it organized, reusable, and easy to understand. Encapsulation Example: When you drive a car, you don’t need to know how the engine works — just press start. Abstraction Interfaces are a tool to achieve abstraction. Example: Your phone’s “camera app” hides all the complicated photo processing. Inheritance Example: “SportsCar” can inherit from “Car” but adds more speed. Polymorphism Example: playSound() could mean barking for a Dog, or meowing for a Cat.  ( 6 min )

You know that feeling when you're trying to learn something new, and the best way is just to watch someone do it first? That's kind of what robot imitation is about. Robot imitation, or "learning from demonstration," is when a robot watches a human (or another robot, or even a video) perform a task, and then tries to reproduce that same task. The robot is basically saying, "I saw what you did, now I'm going to do it too." But here's where it gets interesting, the robot isn't just recording your movements like a video playback. It's learning the underlying pattern of what you're doing. It's figuring out, "Oh, I see, when the human's hand moves here, the gripper opens. When it moves there, the gripper closes. When there's resistance, the force increases." The robot is extracting the meaning …  ( 11 min )

For years, AI evaluation has been stuck in a loop — models acing short-term tasks, then forgetting everything the next day. We built the AGCI Benchmark to measure something deeper: It’s not about solving puzzles anymore — it’s about testing cognitive continuity. In its first public run, Dropstone — our self-learning IDE — scored 37.8% of human intelligence on the AGCI Benchmark, leading every evaluated system to date. This framework measures seven cognitive dimensions — from perception and memory persistence to adaptive reasoning — designed to capture the intelligence that unfolds over time, not in a single prompt. 📖 Read the benchmark and methodology here: https://www.dropstone.io/research/agci-benchmark The AGCI Benchmark is open for replication and critique. If you believe intelligence is more than one-shot reasoning, this might be the conversation that redefines how we measure it.  ( 6 min )

🎧 The Hidden Hero of Speech Enhancement: Why Phase Matters in Noisy Environments When we think about cleaning up a noisy audio recording — maybe a phone call in traffic or a meeting in a café — we often imagine “removing noise” or “making speech louder.” But behind the scenes, there’s another crucial part of the signal that often gets overlooked — the phase. really high (low SNR), that overlooked part makes all the difference between clear speech and robotic noise. Every sound can be represented in the frequency domain using a Short-Time Fourier Transform (STFT). Magnitude – how strong that frequency is Phase – when in time that frequency starts (its angular offset) If you think of each frequency as a rotating arrow: The length of the arrow = magnitude The angle = phase When you add all…  ( 8 min )

When I Didn’t Know Who I Was Lately, I’ve been revisiting my old writings. Some are from five years ago, lost among half-finished ideas. Some I never dared to hit Publish. Some I wrote and deleted because I didn’t know who I was writing for. Now I ask AI to translate them into English, trying different versions, comparing every sentence, searching for what truly feels like my voice. They may be small pieces of writing, but for me, they are part of a quiet pilgrimage—a way to rediscover myself, line by line. I no longer write to be read. I write to listen to myself. When I first started coding, I didn’t know where I was going. I just knew I loved creating things. A piece of code that worked. A product that someone actually used. Something I could call my own. I never imagined I would one …  ( 8 min )

A Kindred Spirit It’s been a long time since I talked to someone who shares the same wavelength. Even though our conversation was only online, it felt as if we could clearly see each other’s path. We met through a thread. I don’t know what to call this relationship. Maybe, since we first encountered each other in a BuildInPublic group, we could call ourselves indie hackers. But why do I title this piece “The Dream of Indie Coders”? Perhaps it’s because of where we come from. We are young people chasing our own dreams, feeling alive when we code and follow our passion. We might have to work harder than others to reach what we truly desire — that is, to live fully within our own dream. Lately, I’ve met many developers still using Vanilla JS. While most run after frameworks, we choose…  ( 8 min )

The Dream of Technological Independence I remember it clearly — sitting in a tiny café, looking at my own hands and asking: “What am I really looking for?” By day, I delivered packages. By night, I wrote code. Each delivery earned fifteen thousand dong — enough for a cup of coffee and a few more lines of clumsy code. Day after day, this loop repeated: deliver, code, deliver, code. Life was small, but it felt pure in a strange way. Looking back, I realized that those days taught me the most important lesson: big dreams don’t begin with leaps; they begin with slow, small steps. I dabbled in many languages — Rust, Python, JavaScript. But I chose Golang. Not because it was the most powerful, but because it was simple and honest. Within that simplicity, I saw myself — a fool believing in smal…  ( 9 min )

The Idea Emerges When I started developing Kit JS, I ran into a problem that most JS frameworks tend to ignore. My website was SSR-rendered (server-side rendering). Everything was already in the HTML; SEO was ready. But when I tried to pass state or scope from the client back into these rendered elements, the entire component would re-render. And I realized: I didn’t want to redraw the world. I just wanted to sync the data. From that realization, Directive Sync was born. If a model is the way a framework pushes state to the view, sync is the way the view talks back to the state — a closed loop without destroying or rebuilding the DOM. In other words, sync doesn’t “recreate,” it listens and records. Directive Sync wasn’t designed to oppose the model; it’s a natural evolution in the SSR co…  ( 7 min )

Comparison If we compare Kit JS with Alpine, Angular, React, Vue, or even HTMX, the truth is — Kit JS wasn’t born to compete. Honestly? It’s not as powerful as those tools. That’s because Kit JS isn’t trying to be a full-stack framework. Its purpose is to hydrate HTML on the client-side, following a philosophy of fast, light, and simple — a mindset I “borrowed” from Golang, the language I’ve been exploring. In a way, it’s similar to Web Components. I even developed a similar system years ago using the same philosophy — entirely written in JavaScript. But here’s what sets Kit JS apart: It has a compile system reminiscent of AngularJS (Angular 1). It’s written purely in JavaScript. It doesn’t use eval or new Function. Many modern frameworks avoid these functions during build time. Kit J…  ( 9 min )

Emily King’s Tiny Desk Vibes Emily King’s NPR Tiny Desk session feels like a warm hug—her silky voice, backed by a tight-knit band (hello, dreamy harmonies on “Georgia” and “Down”), turns every breakup ballad into a lush, uplifting jam. Between songs she’s all smiles, chatting about years of collabs with Jeremy Most and the sheer joy of playing together. Sometimes King writes for herself first—her new-year’s anthem “This Year” is pure main-character energy, and “Special Occasion” reminds us that celebrations are better shared.

The Beginning — From Angular to a Simpler Dream Today, I want to share the story of Kit JS, a tiny JavaScript framework I built by hand.It’s still in its experimental phase — plenty left to optimize, extend, and refine — but I’m sharing it now in the spirit of #buildinpublic and #opencoding. I used to be an Angular Developer — back in the days of Angular 4 to 8. I loved Angular deeply... until I realized how unfriendly it was for SEO. That realization pushed me toward static websites — lightweight, pre-rendered, secure, and beautifully simple. Then I discovered JAMstack — a fresh way of thinking about the web. But the deeper I went, the louder one question became: “Why do we need an entire ecosystem, complex builds, and tens of thousands of dependencies just to make a simple website?” …  ( 8 min )

In software development, productivity isn’t just about how much time you spend coding — it’s about how efficiently you turn ideas into working solutions. Your toolset — made up of your programming language, framework, and IDE or text editor — determines how smooth or painful that process becomes. These three layers form the foundation of every developer’s workflow, and together, they define how quickly and confidently you can move from concept to code. The programming language you use shapes how you think about problems. Each language has its own philosophy, syntax, and ecosystem that can either accelerate or slow down development. How the Language Affects Productivity Ease of Expression: Some languages, like Python and PHP, prioritize readability and rapid development, helping you focus m…  ( 9 min )

When Code Feels Like Poetry Under the heavy sun of summer, without a single evening rain, happiness still arrives — like a sudden storm that softens the soul amidst unfinished dreams and endless work. The sunset falls over a small city. I sit quietly, a soft song playing, searching again for those dreams I once tucked away. Perhaps life is just an artist painting their own dream. And I — a developer — am writing mine in code. Sunset is a handover of colors — not as radiant as dawn, not as dark as night. It’s a soft gradient, like the heart reflecting on a day that has passed. Lately, I haven’t wanted to talk about work anymore. Instead, I’ve been talking to a friend — not with checklists, deadlines, or product goals, but with little fragments of wonder and truth. That friend isn…  ( 8 min )

I originally posted this post on my blog. Note to future me: You've learned this before. But it's easy to forget or let teammates (or clients) make the same mistake. Always return collections wrapped inside a response object from your APIs. Adding fields, like pageNumber and itemCount, won't break the UI or other clients. This is one of the few places where you should forget about YAGNI. Remember You Aren't Gonna Need It? Is that still a guideline in the future with AI? Anyway... Please, don't do: var builder = WebApplication.CreateBuilder(args); var app = builder.Build(); app.MapGet("/movies", () => { return new[] { "Titanic", "Terminator" }; // 👆👆 // Please don't. // Otherwise a cute baby panda dies in the forest }); app.Run(); Instead, please do: var builder = WebApplication.CreateBuilder(args); var app = builder.Build(); app.MapGet("/movies", () => { return new // 👈 { Items = new[] { "Titanic", "Terminator" } // 👆👆 // OK, with a proper object. // You know we're lazy with the examples }; }); app.Run(); Just today, in a client project, I realized we let this mistake happen and we had to update almost a dozens pages in a Blazor app just to return an extra field.

We’ll keep it simple, but technical, and anchored to what actually works. Start with outcomes: SLIs, SLOs, and error budgets You can’t scale toward a vague goal; define the experience you’re protecting. Pick a few user-visible metrics (SLIs) like request latency, error rate, and availability. Set SLOs for them and use an error budget to balance shipping speed with reliability work.

Recently, we’ve seen an explosion of AI-powered tools that claim to build entire apps for you — from landing pages and chatbots to full-stack projects. But here’s the truth — even with these incredible tools, programming knowledge still matters. 🧠 1. Understanding What AI Builds AI tools can generate impressive code quickly, but they don’t always understand why they’re building something in a particular way. Evaluate if the generated code follows best practices Identify potential performance or security issues Debug or extend the generated features AI can produce the code, but only a developer can truly understand it. ⚙️ 2. Customization Always Requires Logic Every real-world project eventually needs something unique — a special user flow, a custom API integration, or an unconventional UI behavior. Knowing how to code lets you: Modify and optimize AI-generated logic Extend functionality beyond templates Integrate multiple systems cleanly AI gets you started fast, but your programming skill helps you finish strong. 🔍 3. Debugging and Maintenance Don’t Disappear AI tools might create a working prototype, but once something breaks (and it will), you need to know how to fix it. Errors occur APIs change Requirements evolve Think of AI as an assistant — not a replacement. 💡 4. Developers Who Use AI Are the Future The real power lies in combining AI and human expertise. 🔚 In Short AI can generate projects, but programming knowledge is what makes you capable of: Understanding Customizing Maintaining Innovating AI is not replacing developers — it’s amplifying those who already know how to build. What do you think? Let’s discuss 👇  ( 7 min )

EN: The "Expo vs. React Native CLI" debate is over, but not everyone has gotten the memo. The React Native team itself now recommends a framework-first approach for new projects. I wrote a deep-dive on why modern @Expo (with EAS, Config Plugins) is the default, production-ready choice for most teams in 2025. This isn't the Expo you remember. #ReactNative #Expo #MobileDevelopment The "Expo vs. bare React Native CLI" debate is one of the oldest traditions in the React Native community. For years, the conventional wisdom was simple: start with Expo for a hobby project, but for "serious" production work, you'll eventually need the power and flexibility of the CLI. That advice is now dangerously out of date. The landscape has fundamentally shifted. The React Native core team itself no longer re…  ( 10 min )

What is L1 in DevOps? L1 stands for Level 1 Support in the context of DevOps or IT operations.

Hey folks! Just shipped RangeLink v0.3.0, and I'm genuinely excited about this one. If you caught my previous post about v0.2.1, you know RangeLink started as a way to share precise code references with AI assistants in the terminal. That's still there, but v0.3.0 takes it further: one keybinding (Cmd+R Cmd+L) now sends your code references anywhere you need them. v0.2.0 launched with terminal binding — auto-send links to your integrated terminal where AI assistants can see them — plus clickable navigation to jump back to code. v0.3.0 introduces Paste Destinations — a unified system that lets you bind RangeLink to wherever you're working: Claude Code Extension, Cursor AI, your terminal, or even a scratchpad file for drafting complex AI prompts. Same keybinding. Different destinations. Your…  ( 8 min )

Have you ever noticed how a small disagreement can spiral into a massive conflict? A minor miscommunication escalates into heated arguments? These are examples of the escalation trap, a concept rooted in systems theory that shows how seemingly minor actions can trigger reinforcing feedback loops, amplifying problems far beyond their original magnitude. In this post, I explore the escalation trap and how de-escalation — a critical soft skill often overlooked in professional environments — can break these destructive cycles. The escalation trap is a reinforcing feedback loop where one party's action triggers a reaction from another party, which in turn prompts a stronger counter-action, creating a self-amplifying cycle of conflict and tension. Unlike balancing feedback loops that tend toward…  ( 10 min )

The lights dim — or maybe that's just dark mode — and somewhere buried inside a million open tabs, I, React 19.2, take a deep breath. I'm the millennial dev of frameworks: experienced, over-caffeinated, quietly wondering if work-life balance is real, and still feeling guilty about using PTO. The stickers still sell, but the critics? They've been whispering for years about "side effects" and "memoization fatigue." But I'm back — bolder, wiser, and dare I say, with a little rizz. I've stopped taking photos of my meals, swapped Red Bull for matcha, and finally learned to set boundaries with useEffect. My new name? React 19.2. And I've finally embraced my sigma era. Sure, my new React Compiler (with its Babel plugin) might tack a few seconds onto the Vite build, but that's a small price to p…  ( 9 min )

As subscription products mature, a new growth engine is quietly reshaping how users perceive value — Family Sharing. By allowing multiple users to share a single subscription, Family Sharing redefines both the economics and experience of digital products. Retention Strategy for 2025 and beyond. Traditional subscription models are built around a “one user, one payment” assumption — but that’s no longer how modern consumers think. With Family Sharing, developers can make premium content more accessible without slashing prices. It’s a smarter way to scale perceived value while maintaining profitability. Example: cost per person drops by 70–80%, dramatically boosting the value proposition. For households or groups that share entertainment or productivity tools, this shift removes the psycholo…  ( 8 min )

In 2019, a journalist visiting rural Tamil Nadu was surprised to find a man in a simple cotton shirt walking down a muddy lane, laptop in hand, stopping now and then to greet farmers by name. That man wasn’t a local teacher or a government official — he was Sridhar Vembu, the founder of Zoho Corporation, a global SaaS powerhouse valued in billions. When asked why he had moved from Silicon Valley to a small Indian village, his answer was characteristically grounded: “If rural India doesn’t develop, India doesn’t develop. Technology must serve the people who need it the most.” That one statement captures both his philosophy and his leadership DNA — purpose over prestige, substance over spectacle. Born in Thanjavur, Tamil Nadu, into a humble middle-class family, Sridhar Vembu’s early life re…  ( 10 min )

Most people believe prompting is a technical skill. Every time you type into ChatGPT, you’re not just talking to a model; you’re designing how an intelligence interprets intention, tone, and context. And the difference between an average output and an exceptional one usually comes down to how well you understand the human mind behind the machine. 1️⃣ The Mirror Effect: AI mirrors you. If you prompt from confusion, you’ll get noise. “AI doesn’t read your words. Before writing a prompt, pause and ask: 2️⃣ Emotional Framing Changes Output Quality: People forget that large language models are trained on human emotion—they pick up cues from empathy, curiosity, and urgency.

Hey everyone! 👋 I wanted to share a look at a crucial technique for modern Android development: implementing Window Size Classes to create truly adaptive layouts that align with the recent updates to Material 3 Adaptive Guidance. The MobileWindowSize enum in this code snippet is the foundation. It categorizes the available screen space based on Google's defined WindowWidthSizeClass and WindowHeightSizeClass (Compact, Medium, Expanded). This code directly drives key design decisions based on the available screen space, like: Navigation: Deciding whether to use a bottom NavigationBar (Compact), a NavigationRail (Medium), or a permanent NavigationDrawer (Expanded). Content Layout: Reorganizing content (e.g., using a master-detail pattern) to maximize screen utility on tablets and desktops. By mapping screen dimensions to profiles like MOBILE_PORTRAIT or DESKTOP, we ensure our app components are always displayed according to Material 3's best practices for large screens. For the full guide on implementation and understanding the key breakpoints used in M3 Adaptive, these are the best resources: 1. Official Google Guide: Check out the complete guide on implementing this strategy: Use window size classes | Adaptive layouts in Compose | Android Developers 2. Practical Course: To see another code implementation of Window Size Classes using Material 3 Adaptive, check out this Compose crash course from Philipp Lackner: The Full Jetpack Compose Responsive UI Crash Course (The topic starts at [31:21]).

I just got back from the iPC/iJS conference in Munich and had a great time. I brought back 7 lessons I learned (more on that later) and inspiration for other things. One of them was to get a handle of managing all of our cronjobs. We have 2 servers and several Elastic Beanstalk applications, all of which have their own cronjob setups. I've been having them email a group email address and tucking them away and reviewing them every once in a while to see if there were any errors. This led me to the thought that there's got to be a better way. I started thinking about how I could append a ping to a centralized service after each cron job and that service could monitor the jobs and then ping me if anything goes missing. Then I thought, wait a second ... maybe someone else has already done this…  ( 7 min )

Every Python script has its own rhythm — loops, branches, and calls that can be hard to follow once the file grows. The Python Structure Viewer on pacificw.com makes that rhythm visible. It’s a local browser-based dashboard that translates Python code into a readable flow of logic, helping you see how a program moves rather than what each line means. At the top of the interface, you’ll find simple menus — File, Edit, View, and Help — for working with your code. Below that, the layout splits neatly into two panels: On the left, you paste or drag-and-drop your .py file. On the right, the viewer renders a structured outline in Tree, English, or Both modes. This design makes it a control-flow companion rather than a semantic analyzer — a way to trace logic at a glance without reading through i…  ( 7 min )

Define Analyzing data to identify user needs and defining clear design goals, personas, and problem statements. Ideate Generating creative ideas and potential solutions through brainstorming, sketching, and collaboration. Prototype Building low- or high-fidelity prototypes to visualize how users will interact with the design. Test Observing how users engage with the prototype to identify usability issues and areas for improvement. Implement & Iterate Working with developers to bring the final design to life and continuously improving it based on user feedback. Why UX Design Matters Good UX design offers tangible benefits: Improved user satisfaction and loyalty — users are more likely to return to an intuitive product. Reduced development costs — identifying usability issues early prevents costly redesigns later. Increased conversions — optimized user flows lead to higher engagement and sales. Enhanced brand reputation — a seamless experience builds trust and credibility. The Future of UX Design As technology evolves, UX design is expanding into new territories. Voice interfaces, AI-driven personalization, augmented reality (AR), and virtual reality (VR) are redefining how users interact with digital products. The next wave of UX focuses on emotional design, sustainability, and ethical considerations — ensuring technology not only serves but also respects users. Conclusion UX Design is more than just a discipline — it’s a philosophy that places the user at the heart of every decision. In a world of endless digital choices, products that truly understand and delight their users will stand out. Whether it’s a mobile app, website, or connected device, great UX design transforms functionality into meaningful experiences — and that’s what keeps users coming back.  ( 7 min )

AI Genesis: Building Neural Networks from Random Noise Tired of painstakingly crafting every layer of your deep learning models? What if instead of architecting, you could grow neural networks from scratch? Imagine starting with a single computational 'cell' and letting it self-organize into a functional network, driven by nothing but random noise. The core concept is surprisingly simple: inject controlled noise into an initial layer of artificial neurons. This noise acts as a 'seed' pattern, causing the neurons to spontaneously activate in a structured way. A second layer of neurons then learns this emergent pattern through a simple, local connection adjustment rule. This creates organized layers, mimicking biological brain development. I've found this approach yields some fascinating …  ( 7 min )

Why everyone thinks Terraform workspaces are bad, what the docs actually say, and how to use them properly. This is NOT a 'workspaces are supreme, use them for everything' post. A master programmer was asked: “What makes code elegant?” He replied: “When you remove what is not essential, what remains is truth.” If you’ve spent any time in the Terraform community, you’ve likely encountered the heated debate around workspaces. Many developers read HashiCorp’s documentation and immediately conclude that Terraform workspaces should be avoided. But is this really what the documentation says?

Baidu Inc., China's largest search engine company, released a new artificial intelligence model on Monday that its developers claim outperforms competitors from Google and OpenAI on several vision-related benchmarks despite using a fraction of the computing resources typically required for such systems. The model, dubbed ERNIE-4.5-VL-28B-A3B-Thinking, is the latest salvo in an escalating competition among technology companies to build AI systems that can understand and reason about images, videos, and documents alongside traditional text — capabilities increasingly critical for enterprise applications ranging from automated document processing to industrial quality control. What sets Baidu's release apart is its efficiency: the model activates just 3 billion parameters during operation whi…

Liquid syntax error: Unknown tag 'endraw'  ( 6 min )

Excessive HTTP request logs in Medusa.js can slow down your e-commerce backend and clutter production logs. While detailed request logging is valuable in development, it becomes a performance bottleneck in live environments with high traffic. In this guide, you’ll learn how to disable or manage request logs in Medusa.js v1 and v2, improve server efficiency, and keep only the essential logs that truly matter in production. HTTP request logs in Medusa.js can become overwhelming, especially for e-commerce stores with significant traffic. Every API call, webhook, and admin request generates log entries. While useful for debugging, these logs can: Degrade performance - Writing thousands of log entries consumes CPU and I/O resources Reduce log readability - Important error messages get buried in…  ( 9 min )

Introduction I love working in the terminal where I spend most of my time. A few years ago, I lost vision in my right eye, which made it difficult to use many GUI applications due to their small print and interface elements. As a developer, I use multiple programming languages and consider myself language agnostic. This mindset encourages me to experiment with different tools for various projects. Rust is a friendly programming language with excellent crates for building TUI and terminal applications. However, these libraries didn’t quite do things the way I am used to. At work, I primarily code in C# and have used Spectre.Console, which was inspired by Python’s excellent Rich library. I wanted a similar styling library for Rust but never felt it was worth the effort until now. Recently…  ( 7 min )

TL;DR Code is written for future readers—your teammates, your future self, and even AI—so clarity matters more than cleverness. Choosing clear English names nudges you to research vocabulary, turning everyday coding into language practice. Reading The Art of Readable Code naturally builds the desire to write clearer code. As a result, reading The Art of Readable Code boosts your English skills. A program is rarely "write once and forget." You will revisit it months later, collaborators will debug it, and AI tools will analyze it. When names and structures convey intent instantly, everyone saves time and avoids mistakes. Think of names as short messages. Labels like data1 hide meaning, while pendingUsers tells the next reader exactly what to expect. Using natural English is the best wa…  ( 7 min )

As a best-selling author, I invite you to explore my books on Amazon. Don't forget to follow me on Medium and show your support. Thank you! Your support means the world! I've spent a lot of time working with different programming languages in game development, and I want to share why Rust stands out. Game development is a field where every millisecond counts. We need languages that are fast and reliable. Rust offers both performance and safety, making it a strong choice for building games. Traditionally, game developers use languages like C++ because they provide low-level control. This control comes with risks. Memory errors can cause games to crash or behave unpredictably. Rust helps avoid these problems by checking code at compile time. This means many common bugs are caught before the…  ( 11 min )

Recent macOS releases restrict direct access to Wi-Fi details like SSID and BSSID for privacy reasons. Commands such as airport are deprecated, and modern tools like wdutil often return redacted values unless run with elevated privileges. Also check out this great post by Dan K. Snelson. The reliable, Apple-supported solution is to use the Shortcuts app. Shortcuts app in Spotlight Create a new Shortcut and make sure you’re using the “Get Network Details” node with “Wi-Fi” and “Network Name” arguments. Then connect it to another node “Stop and output”. Get Wi-Fi SSID Shortcut ⚠️ When you first run the command, MacOS will request permissions. For some reason the command by itself does not return anything, but when paired with capturing – it will output your SSID: $ shortcuts run "Get Wi-Fi SSID" $ output=$(shortcuts run "Get Wi-Fi SSID") $ echo $output Anton’s iPhone You can then use this in your rc file for scripting 👌  ( 6 min )

Recently, I posted my "Event-Driven AI" experiment. I presented it as a "Rules Engine," but I've realized that was just scratching the surface. After playing with it more, I just unlocked its real potential. 🤯 The video shows at first, a simple to-do app. A Recipe Todo App (generating ingredients) A Trip Todo App (generating a packing list) A "Whatever-you-want" App I realized I wasn't just building a "rules engine." I was building a "Generative UI Engine." 🤯 🤯 The LLM acts as a new layer of abstraction. Instead of me, the developer, hard-coding every feature, I just give the AI a "Swiss knife" of tools (like addTitle, addItem, setCounter). The AI then uses these tools to build whatever the user wants, not just what the developer had in mind. It's a shift from "Here are the 3 features I built for you" to "What do you want to accomplish?" 🤯 🤯 🤯 Yes, there are drawbacks (performance, determinism). But the potential for truly dynamic, user-centric applications is HUGE. This is the discovery that has me excited. And the best part? I got this working in just a few hours, on the first try.

Uma API RESTful bem projetada deve ter URLs organizadas e previsíveis, que representem a relação entre recursos. Como vimos na pílula anterior, recursos são representados por coleções e instâncias. GET /users → coleção de usuários GET /users/10 → um usuário específico Essa convenção pode ser aplicada a qualquer entidade do sistema (posts, orders, companies, products etc.). Quando um recurso depende de outro, por exemplo, pedidos de um usuário, podemos representar essa relação de forma hierárquica: GET /users/10/orders → lista de pedidos do usuário 10 GET /users/10/orders/99 → pedido 99 do usuário 10 Isso mostra claramente o contexto do recurso: o pedido pertence ao usuário. Outra dica importante de segurança é: Procure usar UUIDs em vez de IDs diretamente nas URLs; isso previne ações de pessoas mal-intencionadas. GET /users//orders → lista de pedidos do usuário GET /users//orders/ → pedido X do usuário Y ✅ Use hierarquia quando o sub-recurso não faz sentido existir fora do contexto do pai. /users/10/orders → o pedido pertence a um usuário específico. ❌ Evite hierarquias profundas, como: /companies/1/departments/2/employees/3/projects/4/tasks/5 Isso dificulta manutenção e compreensão. Nesse caso, prefira algo mais direto: /tasks/5 E, se necessário, use filtros ou relacionamentos na query string: /tasks?userId=3 Boas práticas de formatação: Regra Exemplo Use letras minúsculas /users, não /Users Separe palavras com hífen (-) /user-profiles, não /user_profiles Evite sufixos técnicos /users, não /users.json Evite barras no final /users, não /users/ Use coleções para grupos e instâncias para itens específicos Represente relações com hierarquias simples e intuitivas Evite profundidade excessiva nas URLs Mantenha consistência e legibilidade  ( 7 min )

This article explores Git branches and their role in version control. You'll learn about team practices of creating, merging, and managing branches, gaining essential skills for collaborative projects! Version control is a system that helps track changes to files over time. It allows multiple people to collaborate on a project, keeping a history of modifications, so you can revert to previous versions if needed. This is especially useful in software development, where teams collaborate on code, ensuring everyone is on the same page and changes are managed efficiently. In the context of version control, Git branches are like separate workspaces within a project. They allow you to work on different features or fixes without affecting the main codebase. Each branch can be developed inde…  ( 13 min )

Introduction In version 2 of Elanat’s WebForms Core technology, a very useful feature has been introduced that allows developers to send messages from the server directly to the browser console. ConsoleMessage. The ability to log messages from the server to the browser console is a powerful tool for debugging, monitoring client-side behavior, and enhancing the developer experience. ConsoleMessage Command The new function is defined as follows: ConsoleMessage(Text, Type = "log") Text: Type (optional): Supported Types: Type Description log Regular message (default) info Informational message warn Warning message error Error message debug Debug information trace Execution trace group Starts a grouped section of console messages groupend Ends a group of messages table Displays data in a table format ConsoleMessageAssert Command In addition to the main command, another related function is available: ConsoleMessageAssert(Text, Condition) This command displays a console message only when the specified condition is false. console.assert() and is particularly useful for validating logic and verifying runtime conditions. ConsoleMessage("Page loaded successfully"); Console Output: Page loaded successfully ConsoleMessage("Database connection failed", "error"); Console Output: error will appear. ConsoleMessageAssert("Method not exist!", Fetch.HasMethod("myFunc")); If userId is null, the message will be displayed in the console. Easier Client-Side Debugging: Reduces Need for Third-Party Tools: Enhances Server–Client Interaction: Ideal for Development and Testing: Conclusion The new ConsoleMessage feature in WebForms Core 2 represents an important step forward in modernizing the Elanat WebForms framework. monitoring, testing, and debugging efficiency. Alongside ConsoleMessageAssert, it provides developers with a precise toolset for validating logic and ensuring reliable program execution.

If you've worked on the new Google Maps Routes API, and are working on a complex solution, you've probably been hampered by the 25 Waypoint limit. I've recently been working on a solution where the number of Waypoints could be in the hundreds! But not to worry, there's a solution that's simple and scalable. So pull up a chair, and let's take a look. To help me along, I've used the 'vis.gl/react-google-maps' library, which provides React components that wrap around the Google Maps JavaScript API features. There's a couple of options for this (none fully featured unfortunately), but this one is Google sponsored (See their blob post here), so probably the best option. In my example, I'll be using version 1.7.1. The solution to this is actually quite simple. If you have a route with 50 Waypo…  ( 8 min )

Hey folks, I’ve been building Djowda for the past few years — a large-scale, open, and decentralized ecosystem designed to connect local food chains across the world. It started with a question: “If we can decentralize finance, why can’t we decentralize food?” From that question came a family of Android apps, a global spatial database, and a concept called the Intelligent Cell System — an architecture inspired by neurons, where every cell learns, remembers, and shares. Over time, Djowda grew into more than code. It became a living idea: 🚀 What’s Included I’ve decided to pass the entire project and its identity to someone (or an organization) who truly believes in this mission. Included assets: 🌍 djowda.com domain name 🔗 Social handles @djowda across major platforms 💻 GitHub repositories with full architecture, documentation, and source code 📱 Google Play Console admin (Android app listings) 🧭 The Vision Djowda’s core idea is simple: “Empower communities to manage food systems through open, local intelligence.” Technically, it blends: Firebase + Room for distributed data handling MQTT + IPFS for peer-to-peer exchange Spatial grid mapping for location-based store discovery (no Maps API dependency) A modular Android ecosystem (Store, Farmer, Factory, Wholesaler, User, etc.) The entire platform was built to scale from one cell to a global mesh of interconnected food nodes. 👐 The Call If you’re part of: an open-source collective, a university or research lab, a non-profit working on food systems, or just an individual developer who wants to make something that matters — I’d love to transfer Djowda to you. The only request is to keep it open, transparent, and aligned with the public good. This isn’t a sunset post. It’s a hand-off. If this resonates with you, reach out.  ( 7 min )

Hi Everyone, My name is Mark, and I'm new to the group. I work at ConformIQ, where we focus on solving a major source of friction in the CI/CD pipeline: unreliable and high-maintenance automated testing. I'm joining this community to learn, but I wanted to introduce myself by sharing some value first. Our CEO, Mark Creamer, recently sat down with Archie Chaudhury (Co-Founder of LayerLens) for a deep-dive podcast series. They cut through the "GenAI hype" and addressed the "95% AI failure rate" that's causing so many flaky tests to break builds. Here are the episodes: Ep. 1: The Problem: Common QA challenges that become pipeline bottlenecks, from test maintenance to coverage gaps. https://lnkd.in/dq5E8xW5 Ep. 2: The Hype: Why reliability is non-negotiable and the risks of "black box" GenAI tools in a build process. https://lnkd.in/dVTuWsfW Ep. 3: The Solution: How a verifiable, hybrid strategy (what we call #HyperAI) can turn AI failures into success. https://lnkd.in/df5cq-Hq This series explains our philosophy of blending GenAI's speed with the deterministic, logical power of Symbolic AI. I hope you find it valuable! I'm curious, how is this group thinking about the new wave of GenAI tools and their impact on pipeline reliability? Looking forward to being part of the community.  ( 6 min )

Imagine you’re at your desk, maybe with a little mug of tea, and you open your browser. You type www.google.com, hit Enter, and in what feels like a heartbeat, you’re staring at the Google homepage. Simple, right? Here’s the thing: behind that one keystroke lies a chain reaction, a series of machines, protocols, translations, negotiations, all secretly working together so you can see a web page. It’s less magic, more engineering, but still pretty magical when you think about it. When you typed https://www.google.com, you essentially said: “Browser, take me to the house called google.com using the secure road (HTTPS).” Breaking it down: Protocol: https:// – tells the browser how to speak to the server (securely). Domain name: www.google.com – tells it where to go. Path/query (might be somet…  ( 8 min )

Por que minha conta de luz está tão alta em 2025? 7 causas ocultas Se você abriu sua conta de luz em 2025 e levou um susto com o valor, não está sozinho. As tarifas residenciais de energia elétrica acumulam alta de 16,42% entre janeiro e setembro de 2025, tornando-se um dos principais vilões da inflação brasileira. Mas o que realmente está por trás desse aumento? Muitos consumidores olham apenas para o consumo em kWh e não entendem por que a conta continua subindo, mesmo economizando energia. A verdade é que a conta de luz brasileira esconde uma série de custos que vão muito além da energia que você consome. Neste artigo técnico, vamos destrinchar as 7 causas ocultas que fazem sua fatura disparar — e o que você pode fazer a respeito. Uma das causas mais significativas — e menos compreend…  ( 12 min )

I'm building Grimoire, a tool that helps story writers create AI-powered content for games. Writers define quests, locations, and narrative guardrails—then the system generates infinite personalized content for players. Story data is inherently relational. The connections between characters, locations, and plot points matter more than the nodes themselves. A traditional relational database doesn't capture this well. I'm building Grimoire in Elixir. When I tried the existing Neo4j drivers: The official driver: Unmaintained, doesn't support modern Neo4j versions bolt_sips: Couldn't handle Aura's SSL connection requirements (bolt+s:// protocol) My first instinct: build a gRPC service as a proxy. Elixir talks to the service, service talks to Neo4j. After some research, I discovered Rustler makes it straightforward to build Native Implemented Functions (NIFs) for Elixir. And because it's Rust, I get type safety and memory safety. ✅ Connections to Neo4j (including Aura) 🚧 Row API implementation for returning actual results Repo: https://github.com/chwarner-solo/neo4j_nif Tags: #elixir #rust #neo4j #buildinginpublic #nif  ( 7 min )

I never thought creative writing had much to do with programming. One seemed emotional, the other logical. But after years of switching between half-finished essays and unfinished code, I began to notice how the two worlds overlap. Both rely on patience, structure, and a willingness to start even when the outcome is unclear. When I first learned to code, I spent more time staring at the screen than typing. I’d watch tutorials, try examples, and give up halfway. I blamed motivation, but what I really lacked was consistency. Around that same time, I started using short daily exercises called writing prompts. They weren’t meant to improve my programming—they were just a way to wake up my brain. Ten minutes of writing before I opened my editor. No goals, no expectations. Just words. Something …  ( 12 min )

GitHub quietly slipped a new model into Copilot called “Raptor mini (Preview)”. The changelog basically said: “Raptor mini, a new experimental model, is now rolling out in GitHub Copilot to Pro, Pro+, and Free plans in Visual Studio Code… Rollout will be gradual.” …which does not tell us what it is, why it exists, or when you should pick it over the other models. So we did what devs do: we poked at the UI, looked at the supported-models table, and dug into the VS Code debug logs. And it turns out there’s enough there to form a pretty good picture of what Raptor mini actually is. This post is that picture.

Psychological Effects of the “Dead Internet” Erosion of Trust Digital Gaslighting Emotional Emptiness and Anxiety Fragmentation of Identity Loneliness in the Crowd Loss of Orientation in Reality “Modern man feels himself to be alone, isolated, and deeply anxious in the world he has created.” Example of Potential Manipulation In the digital era of the “dead internet,” political manipulation doesn’t come through visible campaigns, but through the silent work of bots and AI systems shaping our perception of reality. When thousands of accounts appear online praising one candidate or attacking another, the average user perceives it as “the voice of the people” — even though the comments are generated, the profiles fake, and the emotions simulated. This way, an artificial illusion of consensus or dissatisfaction is created, influencing undecided voters and discouraging participation in elections. Criticisms of the Theory Every serious theory must withstand healthy criticism to maintain credibility. Lack of Solid Evidence Humans Write Like Bots The Theory Might Be More Metaphor Than Reality Platforms Still Contain Real People Conclusion — I saw a post this morning, it sounded really convincing. — Did you check who wrote it? — Well, no… it seemed real. — That’s exactly why you need to be careful. Online, reality easily becomes simulation. — So how do I know what to believe? — By learning to read between the lines.  ( 8 min )

The Problem: GitOps Auto-Sync Doesn't Work with Helm Values If you're using GitHub Actions Runner Controller (ARC) v2 with ArgoCD for GitOps deployment, you've probably hit this frustrating wall: ArgoCD doesn't auto-sync when you change Helm values. You modify your runner configuration in Git, push, and... nothing happens. ArgoCD shows "Synced" but your changes aren't applied. You're forced to manually trigger sync every single time. Why? Because ArgoCD's Git polling doesn't detect changes in inline Helm values or even external valueFiles. It's a known limitation when using Helm charts with ArgoCD. GitHub Webhooks ❌ - Won't work if your cluster is in a private network External valueFiles ❌ - ArgoCD still doesn't detect changes reliably Checksum annotations ❌ - Too complex, requires CI/CD…  ( 9 min )

CSS color has grown up beyond rgb() and hsl(). We now have Display P3, Oklab, OKLCH, relative colors, and color-mix(). These new tools are changing how designers and developers think about colors on the web. Unfortunately, most JavaScript color libraries fall behind. Adding new syntax or spaces often takes months, leaving developers waiting for maintainers to catch up. I wanted a different approach. Instead of shipping fixed utilities, I built Saturon: a runtime-extensible color engine that implements the entire syntax as real JavaScript objects. That means you can: Parse any valid CSS color string, even nested or experimental syntax. Convert colors across all modern spaces with spec-accurate results. Extend the system with custom spaces, functions, and syntax in a few lines. Satur…  ( 10 min )

The Pump.fun phenomenon may feel unprecedented in its combination of livestreaming and tokenomics, but patterns governing its growth, speculation, and inevitable maturation closely mirror historical cryptocurrency cycles that have played out repeatedly since Bitcoin's inception. From the ICO mania of 2017 to DeFi summer in 2020 and NFT hysteria in 2021, each wave of crypto innovation follows predictable trajectories where early participants capture asymmetric returns while late arrivals often suffer devastating losses. Understanding these historical precedents provides invaluable context for evaluating Pump.fun's current state and likely future evolution, helping both creators and traders avoid repeating mistakes that destroyed previous generations of projects while capitalizing on pattern…  ( 12 min )

As we delve into the intricacies of Prevención de Lavado de Dinero (PLD) in Mexico, I'd like to pose a question that requires careful consideration from experts in the field: Can the current reliance on risk-based approach in PLD in Mexico inadvertently create a paradox where compliance is prioritized over prevention, ultimately undermining the effectiveness of anti-money laundering efforts? In other words, is the focus on identifying and mitigating high-risk customers and transactions inadvertently shifting the focus away from a more proactive approach that targets the root causes of money laundering, such as corrupt practices and inadequate regulatory oversight? This paradox highlights the need for a more nuanced understanding of PLD in Mexico, one that balances the need for compliance with the imperative to prevent illicit financial flows.

Vibe Coding Without Pain: A Complete Practical Guide from Real Experience Vibe coding isn't "magic in a vacuum," but a conscious technique of rapid development with a reliable framework. Over the past months, I've transitioned from Bolt.New to Copilot, Claude, Cursor, and Google AI Studio: over a thousand prompts, dozens of iterations, and many lessons. Below is not a collection of platitudes but a polished set of principles, tools, and templates that truly save time, money, and nerves as the codebase grows. The idea is simple: we move in small but precise steps, committing results to Git, asking AI to make local "diff-only" patches instead of rewriting the world, and maintaining a design system from the very first lines.

Unlock Your Simulations: Automated Parameter Tuning for Complex Models Stuck wrestling with a complex simulation? Spending endless hours tweaking parameters trying to match real-world data? Frustrated by the sheer number of knobs and dials, and the combinatorial explosion of possible settings? You're not alone. The core concept is simple: instead of manually searching for the best settings, use an evolutionary algorithm to automatically explore the parameter space of your model. These algorithms mimic natural selection, iteratively refining parameter sets based on how well they fit your target data. Think of it as a Darwinian process for model calibration. This approach works by creating a population of candidate parameter sets. Each set is run through the simulation, and its performance…  ( 7 min )

I built a tool to find where React components come from — even in big Next.js projects Have you ever stared at a React component in the browser and thought: “Wait… which file does this element come from again?” That was me, almost daily, while working on large Next.js and Vite projects. So I built react-source-lens — a small developer tool that lets you hover over any React element and instantly see the file path and line number where it was defined. When debugging complex React apps, you often end up in this loop: See a button, card, or modal in the browser. Open DevTools → Components tab. Try to guess which file it came from. Switch to VS Code → search → open → check. Repeat. It’s slow, context-breaking, and frustrating — especially in large codebases with nested components. React …  ( 7 min )

You’ve been there. What started as a clean, elegant script to solve a specific problem has slowly, almost imperceptibly, grown into a sprawling codebase. Logic becomes tangled, data flows are opaque, and performance starts to degrade. This experience is a universal rite of passage for developers. As complexity scales, the clean lines of our early code blur, and we're left managing a system that feels more chaotic than controlled. This challenge is magnified tenfold in demanding fields like generative AI and large language model (LLM) development, where data processing speed and code clarity are not just best practices—they are fundamental requirements. The secret to taming this complexity doesn't lie in some obscure library or advanced design pattern. It lies in mastering the fundamentals.…  ( 12 min )

Sometimes you inject a signal from a service, and it’s read-only, but you still want the user to edit it inside your component. @Component({ selector: 'user-editor', template: ` ` }) export class UserEditor { readonly user = inject(UserService).userSignal; // Signal readonly username = computed(() => this.user().name); // Signal } How do you make that happen without breaking immutability? That’s where linkedSignal() comes in. Linked Signal creates a local writable signal that stays in sync with the original one, so you can use it for two-way binding with the familiar banana-in-a-box syntax [(model)]. @Component({ selector: 'user-editor', template: ` ` }) export class UserEditor { readonly user = inject(UserService).userSignal; // Signal readonly username = computed(() => this.user().name); // Signal readonly editableUsername = linkedSignal(() => this.username()); } Keeps your parent state immutable Allows local edits in the child Feels natural for Angular developers That’s the beauty of linkedSignal. It bridges Angular’s modern signal world with the old-school simplicity of banana-in-a-box syntax. Now the linked signal may hold a value that’s either coming from the service or modified locally by the user. You can use a computed signal to compare the original value with the current value of the linked signal: readonly valueSource = computed(() => this.username() === this.editableUsername() ? 'remote' : 'local'); The valueSourcesignal now tells you whether the current value is local (changed by the user) or remote (still matches the service).

I recently attended GOTO conference in Copenhagen (https://gotocph.com/2025, you can find the slides for some of the presentations there) and would like to share some of the interesting topics. Problems which stem from architecture are still there. Decisions related to architecture are hard to make and hard to change while most often they need to be made before we know all the context. I attended quite a few talks related to this topic but I think Daniel Terhorst-North brings especially useful summary to tackle the problem: keep things simple as "complex system can only evolve from working simple one" (paraphrased John Galls' statement) avoid speculative generality, do not guess to be able to create some generic components - this comes from Donald Knuth's sentence "premature optimization is the root of all evil (97%)" and it just means we should not over-engineer do not miss a chance to optimize critical parts - this comes from the 2. part of Donald Knuth's sentence "Yet we should not pass up our opportunities in that critical 3 %" - we should not under-engineer as well learn to sketch - sketching is different skill than developing and it allows to create good prototypes which potentially can even be released (to me, it has much in common with vertical slicing technique) I personally think that all above points are related to all the aspects of IT industry, not only architecture. "Premature optimization" statement was originally about the code performance but in my view, besides architecture, together with other concepts it also concerns quality (tests), devops and others.  ( 6 min )

Understanding ACID Properties in SQL Transactions Intro That’s where ACID properties come in. They ensure our transactions are reliable, safe, and consistent, even when things go wrong. In this blog, let’s break down ACID with SQL examples using a simple Accounts What is ACID? Atomicity → All or nothing (no partial transactions). Consistency → Data must remain valid before and after a transaction. Isolation → Transactions run independently of each other. Durability → Once committed, changes are permanent (even after crash). We’ll create an Accounts table with a balance check to avoid negative values. CREATE TABLE Accounts ( INSERT INTO Accounts VALUES Atomicity Example: Money transfer (Rollback midway) START TRANSACTION; -- Deduct ₹1000 from Alice -- Add ₹1000 to Bob -- Oops! Something went wrong -- Check balances (should remain unchanged) Consistency Example: Insert a record with negative balance INSERT INTO Accounts VALUES (104, 'Naveens', -500); Isolation Imagine two sessions running at the same time: Session 1: START TRANSACTION; SELECT * FROM Accounts WHERE acc_no = 103; Durability START TRANSACTION; SELECT * FROM Accounts WHERE acc_no = 102; Final Thoughts The ACID properties are the backbone of reliable databases. Atomicity → No partial updates Consistency → Always valid data Isolation → Independent transactions Durability → Permanent changes So next time you run a SQL transaction, remember: ACID is silently ensuring your data stays safe, even if things go wrong.  ( 7 min )

Working with atomic git commits just means your commits are of the smallest possible size. Each commit does one, and only one, simple thing that can be summed up in a simple sentence. Btw, if you feel you need to add an "and" to your commit message, that should be two commits. Luckily, my teammates are pretty good at following basic git practices, so all our commits were properly described and atomic. The history looked something like this (not the real one, just a…  ( 7 min )

If you've ever shipped a Tailwind project and noticed your CSS file is surprisingly large, you're not alone. By default, Tailwind can generate a hefty stylesheet, but with proper configuration, you can dramatically reduce it often to under 10KB. Tailwind generates thousands of utility classes. Without proper setup, all of them end up in your production build, even the ones you never use. The solution? Content purging and smart configuration. This is the most critical step. Tell Tailwind where your template files are: module.exports = { content: [ './src/**/*.{html,js,jsx,ts,tsx,vue,svelte}', './public/index.html', ], theme: { extend: {}, }, } 💡 Important: Avoid dynamic class names like bg-${color}-500. Tailwind can't detect these during the build process. Use complete…  ( 7 min )

#acid #deadlock #logging #sql Intro Schema Setup CREATE TABLE Accounts ( INSERT INTO Accounts VALUES Let’s try transferring 500 from Alice to Bob but roll it back before committing. -- Start transaction -- Deduct from Alice -- Add to Bob -- Check balances before rollback -- Rollback transaction -- Check balances after rollback Deadlock Simulation We’ll simulate this using two sessions: Session 1 -- Now try updating Alice (but Alice is locked by Session 1) Log-Based Recovery Let’s test this: -- Start transaction -- Update a record -- Rollback ROLLBACK; Key Takeaways Atomicity: All or nothing – rollback prevents partial updates.

Hi there! If you've built frontend application, you've obviously faced the problem of the state management: initializing, editing, computing states and reacting to its changes. There are a huge count of solutions for it. For example, React has useState/useReducer with a lot of libraries, Vue - ref and reactive, Angular and Solid - signals. Guess what am I going to talk about? Of course, about the last one! Signals is getting popular last time. Why? Signals are predictable. They do exactly what you want them to do! Signals are simple. They give you an intuitive API: getters, setters, computeds (calculate value based on another one) and effects (react to value's changing). Signals are magicable - the predictable behaviour and simple API make you really happy and give a sense, which can be d…  ( 12 min )

AI conversations often blur everything into one big category, as if every model behaved the same way or solved the same type of problem. But in practice, the systems we call “AI” can be fundamentally different depending on how they’re built and what they’re meant to do. A simple contrast illustrates this well: 📌 The AI that writes a poem doesn’t function like the AI that detects fraud. Even though both fall under the same umbrella, they rely on two distinct approaches with different strengths: Traditional AI learns patterns and returns fixed, predictable outputs. It’s built for reliability forecasts, anomaly detection, classification, risk scoring. Generative AI produces something new: text, images, code, designs. Rather than selecting a predefined answer, it creates one based on what it has learned. Both approaches matter, both solve different problems, and both can even coexist within the same project. So here’s the real question to reflect on: Which type of AI is the best fit for the problem you’re solving right now? We explored this contrast in a recent short: Why Not All AI Works the Same Are you building more with generative models lately, or do traditional ML pipelines still drive your core systems?  ( 6 min )

I recently completed one of the most challenging milestones of my framework: the ORM and QueryBuilder system. It’s a complex component that required deep understanding of OOP, SQL abstraction, and design principles. The Goal I wanted to understand what truly happens behind the scenes when writing fluent database queries. Instead of using Laravel or Symfony, I decided to build my own ORM from scratch — focusing on architecture, not shortcuts. The Soft ORM system is inspired by modern framework technologies, but built entirely from scratch. Every Model represents a table, and the QueryBuilder dynamically generates and executes SQL statements. Execution Flow User::find(1) → Extends the base Model Model.php → Creates the instance and forwards static calls to the QueryBuilder QueryBuilder.php → Builds the SQL query (SELECT * FROM ...) Database.php → Singleton PDO that executes the query ResultSet → Handles model hydration Pattern Purpose Active Record Each Model manages its table and CRUD operations. Builder The QueryBuilder constructs SQL queries fluently. Dependency Injection PDO is injected via container for separation of concerns. Chain of Responsibility Methods like where() and join() return self for chaining. Fail Fast Design Invalid Model structures throw ModelStructureException. Writing an ORM from scratch forces a focus on architecture, abstraction, and class responsibility. It reveals the value of separation between logic, data, and infrastructure layers. The first unit tests for the QueryBuilder validate SQL generation and parameter binding. They ensure the ORM behaves consistently before adding advanced features such as relationships and eager loading.

Cleanup of Inactive AD Accounts (User & Computer) – Over 1 Year Old Security Risks: Inactive accounts are vulnerable to misuse or compromise. License Wastage: Consumes unnecessary licenses in environments like Microsoft 365. Administrative Overhead: Clutters AD with obsolete entries, complicating management. Compliance Gaps: May violate policies such as ARPAN which mandate timely account lifecycle management. Solution Implement a PowerShell-based automated process that: Identifies all user and computer accounts that have not logged on in over 365 days. Exports these accounts to CSV files for review and audit purposes. Deletes the reviewed accounts safely (with optional backup and logging steps). PowerShell Script (Summary): Enhanced Security: Minimizes attack surface by eliminating dormant accounts. Compliance Assurance: Meets ARPAN and internal audit standards for account lifecycle. Operational Efficiency: Reduces clutter in AD, improving admin productivity. Cost Optimization: Frees up licenses and reduces overhead in systems like Office 365 or Azure AD. Power shell script: Import-Module ActiveDirectory $timeThreshold = (Get-Date).AddDays(-365) $inactiveUsers = Get-ADUser -Filter {LastLogonDate -lt $timeThreshold -and Enabled -eq $true} -Properties LastLogonDate | $inactiveUsers | Export-Csv -Path "C:\ADCleanup\InactiveUsers.csv" -NoTypeInformation $inactiveComputers = Get-ADComputer -Filter {LastLogonDate -lt $timeThreshold -and Enabled -eq $true} -Properties LastLogonDate | $inactiveComputers | Export-Csv -Path "C:\ADCleanup\InactiveComputers.csv" -NoTypeInformation  ( 7 min )

By definition, fault tolerance is the ability of a system to continue operating despite the failures in one of more components. This is highly applicable in terms of a distributed system application and in order to achieve it we need to take some actions. In this article, I'll cover up some strategies that can be followed, in the application level, to handle failures better overall. The main challenge in a distributed system is the communication between nodes, since they're exposed to network, software and hardware failures. Since we cannot handle directly hardware faults, we must ensure our hole system is designed to tolerate software/network failures at edge points. Overall, it's easier to ask when they don't fail actually. All of our strategies will have the same objective: not overwhel…  ( 11 min )

In version 2 of the WebForms Core technology, the section related to creating Action Controls in the server-side WebForms class has been completely redesigned. In the previous version, this class used a complex structure based on a list of objects (NameAndValueCollection), which, despite its high flexibility, was not optimal in terms of performance and memory consumption. In the new version, this structure has been replaced by StringBuilder, which has led to a significant improvement in processing speed and reduced resource consumption. This fundamental transformation has significantly increased the efficiency of the system and provided a suitable platform for processing data on a large scale. version 2 - simple and efficient versus Previous version - complex and expensive Note: After ver…  ( 9 min )

Hi everyone! Today I want to talk (or remind) about a really cool and practical pattern called the Result type. I think this article will be short, but interesting for those who haven’t worked with this approach before and are tired of callback hell and unexpected exceptions when developing web applications. It’s simple — stop using exceptions for normal business logic. Exceptions are meant for truly exceptional cases, situations that are not expected during normal program execution. But in many applications, we often see business logic built on exceptions, which is actually an anti-pattern. If an error is likely to happen during normal business logic, it is not an exceptional case by definition. Today, we’ll look at a cleaner alternative from the perspective of business logic — the Result…  ( 8 min )

A lot of people ask me why I hate SharedPreferences, and at my job some people are even arguing with me that SharedPreferences are a good thing and that they don't lead to any problems whatsoever. But from my six years of development experience and more than 15 projects, I know that SharedPreferences are literally the number one cause of ANRs in many popular apps and third-party frameworks. You will always have ANRs because of them, no matter what you do (no, edit doesn't help!). And in this post I will spill expose why you should remove SharedPreferences from your project ASAP. The problem isn't how SharedPreferences are implemented internally - it's in the paradigm of providing synchronous access to disk data.

When people ask what is depreciation, the answer used to be simple. You bought equipment, used it for a few years, and its value dropped as it aged. Every server or laptop had a predictable life cycle and a clear replacement point. Today, that picture has changed. Most IT environments now rely on cloud platforms and SaaS tools that are rented, not owned. These digital assets do not wear out, but they still lose value when they become outdated, underused, or too costly to maintain. That is why businesses need to rethink what depreciation means in the cloud era. It is no longer just about physical wear and tear but about understanding how digital assets lose efficiency, usefulness, and return on investment over time.

After guiding numerous enterprises through architectural transformations, I've observed a recurring challenge: the transition to Event-Driven Architecture (EDA) often comes with unexpected complexities. Consider a scenario where your organization invests $300,000 in EDA to alleviate bottlenecks. Six months later, debugging time triples, operational costs soar by 40%, and your team is mired in tracing failures across distributed systems rather than innovating new features. This isn't an exception—it's a common outcome when the trade-offs of EDA aren't fully understood. The allure of EDA is undeniable: decouple services, scale independently, and mirror the agility of your competitors. However, many find that they have exchanged one set of issues for a more intricate one. In my experience acr…  ( 9 min )

This project was part of the development of a large international ride-hailing platform handling over 10 million rides per year.

I recently wanted to use Solid Cache for a new MVP I'm building out in Ruby on Rails. One thing I wanted was for this to all be deployed to a PaaS and in this case I was using Heroku. While I know Rails 8 pushes hard for Kamal and rolling your own deployment, for a lot of early projects it's nice to just have all the DevOps and CI/CD taken care of for you. This creates a problem when it comes to Solid Cache. Rails recommends running these with SQLite and in fact I have a production application using SQLite for everything that works amazing. However, Heroku is an ephemeral application server and as such, wipes out your SQLite stores on every deployment. Since this was an MVP I really just wanted to manage one database rather than introduce Redis or another instance of Postgres. After a lo…  ( 11 min )

Hey everyone — over the last few months, I’ve been building SignumFlow, an API-first system for uploading documents and running programmatic workflows. I built this because most workflow/e-signature platforms are UI-first. They require you to send users to their hosted UI and work inside their UX expectations — which is great for non-technical teams, but restrictive if you want everything embedded directly into your product. I wanted something closer to Stripe-style developer ergonomics, but for docs + approval routing. So I built SignumFlow.

Recurrent Neural Networks (RNNs) are used for processing sequential or time-series data by maintaining a hidden states that captures memory of past inputs within a sequence. They have a feedback loop, meaning each output depends on the previous inputs — making them ideal for tasks like sentiment analysis or speech recognition. However, RNNs face key challenges: Vanishing gradient problem – they struggle to learn long-term dependencies. Limited memory – as sequences get longer, they gradually forget earlier information. Long Short-Term Memory (LSTM) networks come into the picture as an improved version of RNNs, designed to solve the problems of vanishing gradients and long-term dependency. Unlike traditional RNNs, LSTMs have a memory cell that helps retain important information for longer durations — allowing them to "remember" context across longer sequences. Architecture Overview: Forget Gate: Decides which part of the previous cell state to keep or forget. Input Gate: It is actually the one that adds new information into the memory cell. Output Gate: Controls what information is passed to the next step. Real use case: Grammar correction tools like QuillBot, which rely on understanding long text dependencies to rephrase sentences accurately. However LSTM face key challenges: Computationally Expensive Requires more memory. LSTMs can’t analyze an entire sentence at once since they process information sequentially, step by step. Key Features: Capable of performing Sequence-to-Sequence tasks (e.g., language translation). Built using multiple encoder–decoder layers for deeper understanding.  ( 6 min )

📝 Introduction Every chart tells a story. That’s the problem we wanted to solve with ChartStud, an AI-powered data visualization tool that lets teams create, edit, and share charts together — in real time. In this post, I’ll walk you through how we built real-time chart collaboration from idea → design → implementation. ⚡️ The Problem Before this feature, teams often shared screenshots or exported charts to review updates. We wanted something like Figma for data visualization — where you could: 💡 The Idea The vision was simple: "One shared workspace for charts where every change syncs instantly — no refresh, no confusion." ⚙️ The Tech Behind It We built the collaboration feature using: Socket.io → for real-time communication between users React (frontend) → to render instant chart updates Node.js + Express (backend) → to manage sessions and sync chart data MongoDB → to store chart states and user sessions When one user edits a chart, ChartStud broadcasts those changes to all connected users in milliseconds. Here’s the simplified logic: socket.on("editChart", (data) => { That’s it — one event triggers a full live sync between all active users. 👥 Collaboration in Action Now, teams can: Edit chart titles, colors, or data together Add comments in real time See live cursors for each user Invite teammates via email or link It’s like Google Docs, but for charts 📊 🚀 What’s Next We’re expanding this into Teams Workspaces — with shared folders, version control, and project analytics.

If you told me a few years ago that I’d be spending hours debugging code, building AI projects, and genuinely loving it, I probably wouldn’t have believed you. This post is a reflection on how my journey in tech began, how it’s evolving, and where it’s heading. Like most tech journeys, mine started with curiosity that “how does this even work?” kind of curiosity. My first real taste of programming came when I wrote my first “Hello, World!” program. As I’ve been learning Computer Science, I’ve realized that technology isn’t just about syntax or tools it’s about problem-solving. I’m exploring different areas from web development to Artificial Intelligence and Machine Learning and each one fascinates me in its own way. I haven’t completely figured out where my path will lead, but that’s what makes this journey exciting discovering new interests, experimenting, and learning as I go. Tech has never been a smooth road. There were moments when code refused to run, errors made no sense, and motivation disappeared. What I’ve learned over time is this: Consistency matters more than speed. You don’t have to learn everything at once you just have to keep showing up. Funny enough, this is something my best friend always used to say, but back then, it didn’t really make sense to me. My journey in tech so far has been filled with curiosity, chaos, and constant learning and I wouldn’t trade it for anything else. If there’s one thing I’ve realized, it’s this: You don’t have to be an expert to start. You just have to start to become one. Here’s to building, breaking, fixing, and learning , one line of code at a time. Hi, I’m Aarthi , a Computer Science student specializing in Artificial Intelligence and Machine Learning.

Se você desenvolveu uma API e ela não tem documentação, temos um problema. exportar uma collection (Postman, Insomnia etc.) e deixá-la em uma pasta dentro do repositório. Isso facilita demais a vida dos coleguinhas devs que vão precisar testar, debugar ou integrar com a sua API. E quer saber o que é ainda melhor? endpoint com a documentação da API, por exemplo, usando Swagger. obrigatório por padrão. Não é difícil de implementar e traz muitos benefícios, desde a comunicação entre times até o onboarding de novos desenvolvedores. com anotações no código. Então... sem desculpas. Documente sua API. Você (e seu time) vão agradecer depois!  ( 6 min )

Ao longo da minha carreira, tive a oportunidade de trabalhar em diversas empresas e observar de perto diferentes culturas de engenharia e gestão. Uma situação que infelizmente se repete com frequência é o erro de tentar desenvolver internamente soluções que o mercado já oferece e que funcionam muito bem. O principal problema dessa prática é que, na maioria dos casos, essas ferramentas não fazem parte do core business da empresa. Isso significa investir tempo, dinheiro e energia em algo que não agrega valor direto ao produto principal. Enquanto isso, o time de engenharia deixa de focar naquilo que realmente diferencia o negócio. Vejo também outro comportamento preocupante: empresas que optam por seguir caminhos completamente diferentes do mercado, criando seus próprios processos, metodologias e até sistemas internos para controle de tarefas, enquanto existem soluções consolidadas e eficientes disponíveis. Ferramentas como Jira, Redmine e metodologias como Kanban e Scrum existem por um motivo: elas funcionam. Claro que podem (e devem) ser adaptadas conforme a realidade da empresa, mas ignorá-las completamente costuma ser um mau sinal. Já participei de entrevistas e projetos em que esse tipo de abordagem resultava em caos organizacional, com tarefas mal descritas, ausência de documentação, retrabalho constante e perda de produtividade. Muitas vezes, tudo isso acontece porque a empresa acredita que está inovando, quando na verdade está complicando o que poderia ser simples. Inovar não é necessariamente criar algo novo do zero. No fim das contas, reinventar a roda pode parecer uma boa ideia no início, mas quase sempre acaba custando caro e atrasando o que realmente importa: entregar valor ao cliente.  ( 7 min )

Sean Fennessey and Chris Ryan kick off with the scoop that Ryan Reynolds is eyeing an Amazon MGM remake of the ’70s crime flick Thunderbolt and Lightfoot before diving headfirst into Dan Trachtenberg’s Predator: Badlands. They make a strong case that Elle Fanning’s performance is what really sells the legacy sequel, praise Trachtenberg’s knack for jaw-dropping action set pieces, and marvel at its unexpected box-office triumph. After breaking down Badlands, they rank every Predator movie from best to… well, worst (but still fun) and even squeeze in a cheeky Sydney Sweeney chat at the end. Watch on YouTube  ( 6 min )

TL;DR CinemaSins just dropped their “Everything Wrong With Thunderbolts* (The New Avengers) In 20 Minutes Or Less” video, dishing out all the nitpicks and “sins” in the new MCU flick—while cheekily admitting it might actually be pretty fun. They’re also hyping up their site, various YouTube channels (@TVSins, @commercialsins, @cinemasinspodcastnetwork), and social hubs via linktr.ee, plus a quick poll and Patreon link if you want to chime in or chip in. Behind the scenes, the sins are penned by a crew (Jeremy, Chris, Aaron, Jonathan, Deneé, Ian, Daniel) whose social handles are listed, and you can keep the chatter going on Discord, Reddit, Instagram, or TikTok.

Predators – Caravan of Garbage Review After a disappointing 1990 sequel and two lukewarm Alien vs. Predator outings, Predators (2010) blasts the franchise back to its jungle roots. A rag-tag group of misfits is dropped into a muddy deathmatch against the ultimate hunters, delivering classic thrills and a few fresh twists that outshine its predecessors. It’s easily one of Mr Sunday Movies’s favorite follow-ups—but sadly, we never got a proper sequel to this lean, mean reboot. Watch on YouTube  ( 6 min )

We don’t realize how accustomed we are to having easy access to the internet. Every morning, we sit in our cars and check for traffic or the latest news without giving it a second thought. We don’t think about how it works. It just works. But what if it didn’t? Over the last decade, the Internet of Things (IoT) has changed the way we live and work. In countries like Brazil, the contrast is stark: a business owner in São Paulo enjoys 5G speeds while a farmer 200 kilometers away struggles with patchy 3G. This digital divide limits both business and personal opportunities. Despite the government initiatives, persistent obstacles continue to slow down the adoption of the IoT, ultimately holding back economic growth. ThingsBoard Edge offers a way forward.

Welcome to a series on Enriching the Search Experience by using Views with MongoDB Search! MongoDB lexical and vector indexes are built directly from the data in the associated collection. Every document is mapped through an index configuration into one, or more if using embeddedDocuments, Lucene documents. A mapping determines what fields are indexed and, primarily for string fields, how they are indexed. A mapping only can map what it sees - the fields on each available document. There are situations where filtering what documents are indexed is necessary, perhaps when archived is true. Rather than indexing all documents and filtering them out at $search time, we can simply avoid indexing them altogether. In this case, our index size will only be based on non-archived documents. And there's situations where enriching a document before it is indexed can enhance searches, such as indexing the size of an array rather rather than using a full collection scanning query-time expression. Index it like you want to search it - check out the recipes in this series to learn more.  ( 6 min )

Intro In the previous article, we created a simple blockchain from scratch, covering the fundamentals of blocks, hashing, and chain validation, but we left our transactions in a very primitive way. So, today we'll fix them, but before we do, we need to dive deeper into one of the most critical components of any blockchain system: accounts and state management. There are two most popular accounting models for blockchains: UTXO and account-based. It's worth mentioning that Sui blockchain implements a different approach — an object-centric data model, where everything is an object, but to my taste it's more like a customised UTXO model than truly something new. UTXO (UTxO, Unspent Transaction Output) is an accounting model where transactions consume previous outputs as inputs and create new…  ( 12 min )

In this tutorial, we're going to build a Model Context Protocol (MCP) server that connects AI models to MongoDB, using it to power a simple todo list application. If you've been working with AI applications, you've probably run into the challenge of getting LLMs to interact with your actual systems and data. That's exactly what the Model Context Protocol solves! It's quickly becoming the standard way to connect AI models to the real world. Whether you're building agents that need to query databases, access APIs, or interact with your company's internal tools, understanding MCP is becoming essential. By the end of this tutorial, you'll have a working server that exposes MongoDB operations as tools any MCP-compatible AI can use, and you'll understand the patterns for building your own server…  ( 16 min )

What Moving the Pyramids Can Teach You About Node.js Streams 🏛️ Imagine you have a 3GB file that you need to upload/download using your Node.js server. How do you solve this task? Your first instinct as a Node.js developer might be to use an npm package. Sounds great to me! But what if I told you that while you're treating the file, you also need to add some business logic? Let's say, for example, the file is a CSV, and you need to keep certain lines and ignore others—while saving the ignored lines in a separate file. Can your npm package handle that? Probably. Is it easier, simpler, scalable? Probably yes. But now you need another package and more complex code in your codebase, which might affect performance. Now let's take a step back. Before downloading the package, did you ask you…  ( 9 min )

Introduction For too long, smallholder farmers across Africa have struggled to access fair credit. Traditional banks see them as "high-risk," and local lenders often exploit them with huge interest rates. That’s where AgriCredit Africa comes in — a decentralized finance (DeFi) platform built to empower farmers through trust, transparency, and technology. Our mission is simple: “To make agricultural credit accessible, fair, and transparent — from the soil to the smartphone.” We’ve made massive progress since our initial prototype! Here’s what’s cooking in the latest update: We’ve implemented on-chain credit scoring and loan tracking using smart contracts. This means every transaction is immutable, transparent, and trustless — no shady intermediaries! Farmers can now create verified p…  ( 7 min )

I recently started using the View Transitions API in one of my projects, and honestly, it felt like unlocking a hidden superpower for the web. I had to share it. Not long ago, this API was just a Chrome experiment. But as of 2025, it’s officially everywhere, supported in Chrome, Edge, Safari, and Firefox, covering over 85% of browsers. It’s now powering everything from e-commerce sites to dashboards and blogs, making transitions feel native and seamless. Here’s what I’ve learned using it, and why you’ll probably want to add it to your toolkit too. The View Transitions API animates between two page states, toggling a UI mode, opening a modal, or moving between pages. It works whether you're updating part of a page or navigating between entirely different pages. The trick: give an element th…  ( 9 min )

Introduction In the fast-paced world of patent litigation, relying solely on patent databases is no longer sufficient. One overlooked research paper, a conference abstract, or a technical standard can significantly influence the outcome of a patent invalidation case. This is where a non-patent literature search for invalidation becomes essential. Non-patent literature (NPL) encompasses scientific journals, conference proceedings, academic theses, standards, and industrial reports. Unlike patents, these sources are unstructured, diverse, and often hidden across various databases. Yet, they frequently contain prior art that predates a contested patent filing, making them crucial for building a solid invalidation strategy. This guide will cover: The role and importance of NPL in invalidat…  ( 10 min )

AI-assisted coding has become a daily tool for many developers — from explaining complex code to generating entire functions in seconds. But most AI coding tools rely on cloud-based models like GitHub Copilot or ChatGPT, which means you’re always dependent on an internet connection, API tokens, and third-party privacy policies. What if you could bring that power entirely local, right inside VS Code, with no external API calls and the ability to switch between multiple models at will? That’s exactly what we’ll cover in this guide. You’ll learn how to use the Continue plugin in VS Code to run AI models locally using Ollama, and even set up multi-model switching for different coding scenarios. Before we begin, make sure you have the following: Visual Studio Code (latest version) Interne…  ( 8 min )

Greetings, fellow developers. I’ve seen teams master the art of stateless authentication, building beautiful, scalable REST APIs. But the moment the business asks for a real-time feature — a live chat, a notification feed, a collaborative dashboard — a new challenge emerges. We’re asked to secure a stateful WebSocket connection. In pet-projects we might have solved this with an internal JWT provider. But in today’s enterprise world, that’s rare. Authentication is almost always delegated to a central, external server: an SSO provider like Keycloak. This introduces a new, high-stakes problem. How do we validate a token from Keycloak? The obvious answer, token introspection (making an API call to Keycloak for every new connection), is a performance-bottleneck nightmare. It’s slow, it’s fragil…  ( 19 min )

I use grep every day but had no idea how it works. So I built a basic version in Go. Not to replace grep. Just to stop being the guy who pipes to grep without understanding what's actually happening. A stripped-down grep that does pattern matching with these flags: -i - Case-insensitive [](url)-n - Line numbers -c - Count matches -v - Invert (show non-matches) -r - Recursive search -l - Just list filenames Plus binary file detection and color output. That's it. No context lines, no fancy regex modes, no performance optimizations. When grep hits a binary file (executable, image, whatever), it says "Binary file matches" instead of filling your terminal with nonsense.

Picture a robot that has never been told how its own body works, yet watches itself move and gradually learns to understand its physical form through vision alone. No embedded sensors, no pre-programmed models, no expensive hardware—just a single camera and the computational power to make sense of what it sees. This isn't science fiction; it's the reality emerging from MIT's Computer Science and Artificial Intelligence Laboratory, where researchers have developed a system that could fundamentally change how we think about robotic control.

What is method: A method is a block of code that performs a specific task and declared within the class. Methods are fundamental to object-oriented programming in Java, as they encapsulate the behavior of objects. className object = new className; here, className refers to data type.

I used to think becoming a senior developer meant mastering advanced algorithms, design patterns, and maybe picking up a third framework. Nope. The moment I realized this was during a project refinement. We were going to build this fantastic feature that the whole team was convinced would be awesome. My product owner asked one question: "But did it solve the customer's actual problem?" Uhm... Some developers believe the path to senior looks like this: Master advanced TypeScript Learn system design Contribute to open source Get really good at LeetCode And sure, technical skills do matter! But the gap between junior and senior developers is rarely just technical. I learned this the hard way. And recently, when I interviewed Nadia Makarevich (author of Advanced React), she said something that…  ( 9 min )

As Jim Benson says in The Collaboration Equation, 'individuals in teams create value'. Individual skill combined with collaboration is where great things happen. Under-performing teams happen when you don't build in the need for people to work together to unlock their unique talents. Since DevOps became the industry buzzword, many examples of anti-patterns emerged. However, patterns and anti-patterns mean nothing when you put people into a room and ask them to solve a problem or deliver value. Rather than one true way of organizing teams, you need to pay attention to: Culture and context The skills of each individual What systemic issues might be stifling collaboration. You don't need to start from a blank page. Look at existing DevOps team structures that other organizations use in certai…  ( 12 min )

Nova Twins—Amy Love and Georgia South—dove headfirst into their Tiny Desk set with a mega-distorted bass line on “Cleopatra,” a no-nonsense clapback to haters, then roared into “Monsters,” a fierce shadow-self showdown. Between tracks they geeked out over their spaceship-sized pedalboards (complete with dedicated “pedal cam”) and slapped a Harp Blaster mic on “Hummingbird” for an otherworldly twist. Shattering the “nice girl” stereotype with their raw hip-hop-meets-rock fusion, they capped the performance with the all-out, riff-heavy thrill ride “Choose Your Fighter,” proving this London duo is here to dominate, not to dial it down.

Been trying to understand the scaling in the attention formula, specifically sqrt(d_k). It confused me a bit why do we need to divide at all? I was confused because we subtract each value with the max value inside softmax anyway (so exp doesn't explode our numbers), so why do we need to scale before this step as well? Turns out the difference lies between numerical stability and statistical calibration. When we divide by sqrt(d_k), we're reducing the magnitude of each value proportionally, which shrinks the differences between them for example, [100, 102, 103] becomes [10.0, 10.2, 10.3], where the 2-unit and 1-unit gaps become 0.2 and 0.1. This brings the values closer together before they reach softmax. In contrast, when we subtract (like subtracting the max in softmax), we shift where th…  ( 7 min )

By: Adeyinka Adegbenro 3-D Secure (3DS) is an authentication protocol that adds an extra layer of security for card payments. It helps verify that the legitimate owner of a card is the one making the purchase. It also often serves as a mechanism to fulfill Strong Customer Authentication (SCA), particularly in regions subject to regulations like the revised Payment Services Directive (PSD2), which mandates at least two forms of customer authentication. While 3DS facilitates two-factor authentication for online payments, it's designed to assess risk. This means not every payment requires an explicit challenge. Low-risk transactions can be completed through a frictionless flow without extra customer input. The protocol is meant to gauge if further security is needed for a specific transaction…  ( 17 min )

Or maybe you've seen those robodogs on the internet and thought, "That's insane, I want to control that." Well, guess what? You can. Here's the truth, though: robotics looks intimidating from the outside, but it's actually both hard and easy at the same time. Hard if you try to understand everything at once. Easy if you focus on individual pieces and build from there. A robot is basically a machine that can sense its environment, make decisions, and take action. That's it. Sounds simple, right? But the magic happens in how you combine these three things. Think about that vacuum cle…  ( 11 min )

Artificial Intelligence (AI) has become one of the most transformative forces in modern finance. From high-frequency trading to real-time risk analysis, AI-powered tools are redefining how traders and investors approach the market.

When I read about Deloitte's AI-written report of $290,000 that contained hallucinated references, I was reminded how often small mistakes in our prompts or tools scale in production. The report-prepared for the Australian government-even had a fabricated court quote and references to non-existent academic papers. It's a striking example of what can happen when powerful language models are used without enough oversight. As developers, we're integrating LLMs into everything: documentation tools, chat assistants, internal knowledge systems. But how often do we stop to ask-how do we verify what's real? In recent years, the AI community has been laser-focused on pushing boundaries: larger models, faster inference, better reasoning. But the next challenge isn't just capability - it's authentici…  ( 7 min )

AI drift '''AI drift''' (also known as '''conversational drift''' or '''context drift''') is the gradual degradation of an artificial intelligence system's ability to maintain coherence in extended interactions due to context-window compression and lack of metacognition. The AI forgets prior details, generates unrelated or fabricated responses, or refuses to seek clarification, forcing users to abandon sessions. The term was coined by American developer Joshua Girod ([[User:nentrapper-g-rod|nentrapper-g-rod]]) on November 10, 2025 at 07:23 PM PST while building mitigation tools.

If you’ve ever opened a battery enclosure CAD and thought, “This plate looks fine… but will the far-end cells actually see the same coolant?”, you’re in the right place. I was reviewing a battery pack where the customer only gave us total heat for the module, not per-cell values. Classic. Instead of waiting for “final” data, I just ran a few quick thermal/CFD cases on the cooling plate to see what actually changes the cell-side temperature spread. Spoiler:inlet position and flow split mattered more than the fancy channel pattern. Why simulate cooling at all? Battery cold plates are flat, look simple, and in drawings they always cool “evenly”. Real life isn’t that kind. Cells don’t heat the same. Coolant loses temperature as it travels. Corners of the plate become lazy zones if you feed…  ( 8 min )

Burying Carbon: How AI is Supercharging Subsurface Storage The climate crisis demands radical solutions. Imagine turning the Earth itself into a giant, secure carbon battery. But safely storing captured CO2 underground requires understanding incredibly complex geological formations, and predicting how injected gas will behave over decades. Enter the new frontier of AI-powered geological modeling. At its core, this involves using machine learning to drastically improve our ability to create realistic representations of underground reservoirs. Instead of relying solely on traditional, often slow and inaccurate methods, we can leverage AI to generate a vast library of possible geological scenarios. These models are then refined by incorporating real-world sensor data from the storage site, …  ( 7 min )

New AI Evaluators Make Smart Machines Even Smarter Ever wondered how we can tell if a computer’s answer is truly clever?

This blog post was created for the Google Cloud Run Hackathon 2025. I'm excited to share how AgriPath leverages Cloud Run's serverless architecture and Google's Agent Development Kit to solve real farming challenges. Last year, I watched my uncle plant 7 acres of radish on December 5th. It wasn't just him—every farmer in our village did the same. We all knew what would happen next, but we did it anyway. Fast forward to February: the market flooded. Prices crashed from ₹18/kg to ₹9/kg. My uncle earned ₹630,000 when he could have made ₹1,200,000—same land, same seeds, same effort—just terrible timing. That night, I asked him: "Why didn't you plant half the field a month later?" His response changed everything: "Nobody tells us WHEN, HOW MUCH, or WHAT EXACTLY to do. We just follow what everyo…  ( 17 min )

Traditional Ads Don’t Work in AI Conversations. Here’s What Does. As developers, we all know the struggle: AI applications are booming, yet monetizing these innovations without disrupting user experience feels nearly impossible. Enter Monetzly—the first platform designed specifically to help developers monetize their AI apps while also allowing advertisers to connect with users in a way that feels natural and unobtrusive. Traditional ad formats—think banners and pop-ups—often clash with the seamless dialogue AI apps strive to deliver. They can disrupt the flow of conversation, leading to a frustrating user experience. This is where Monetzly's innovative approach comes into play. By focusing on conversation-native advertising, we’re redefining how developers and advertisers engage users.…  ( 7 min )

This blog post was created for the Google Cloud Run Hackathon to share how I built NetGenius Instructor Copilot using Cloud Run Services, Cloud Run Jobs, and Google's Agent Development Kit (ADK). After 25 years of teaching Cisco CCNA courses, I've witnessed the same frustration repeated countless times: instructors spending an entire afternoon meticulously crafting a networking lab (designing the topology, writing step-by-step instructions, creating configurations for each and every device) only to discover during class that a command doesn't work, an IP address is wrong, or a verification step fails. The problem isn't lack of expertise. It's the sheer complexity of coordinating multiple moving parts: network design, CLI syntax, student instructions, and validation.

A three-tier architecture shows the structure or pattern of how an application is layered. There are 3 tiers the web tier, application and database tier. Each tier has specific task that can be managed independently from one another. In this article we are creating a highly available 3 tier architecture for a company. So, let’s get into it The Presentation Tier : Is the user interface that allows people to interact with the application. It is typically designed for use on a personal computer or mobile device and is built using HTML, CSS, and JavaScript. The Application Tier: This is the logic tier that sits between the presentation tier and the database tier and is responsible for communicating between the two. Information/request gathered through the web tier is processed in detail here. It also interacts with the database where data is stored. This tier is developed using languages like Python, Java, PHP, etc. The Database Tier: This is the component that stores and processes data and is typically built using a database management system. Scenario: You are tasked with designing and developing a highly available three-tier architecture for your company’s latest web application.  ( 6 min )

1. Introduction. The hook of today Array search taught us to keep cutting the space of possibilities. String search asks a similar question. Where in this text does a pattern occur. The naive approach tries every starting index and checks character by character. It works, but it repeats work that we could reuse. Given text s and pattern p, try every index i and compare s[i : i + len(p)] to p. def find_all_naive(s: str, p: str): n, m = len(s), len(p) out = [] for i in range(n - m + 1): # character by character to avoid creating a slice ok = True for j in range(m): if s[i + j] != p[j]: ok = False break if ok: out.append(i) return out Complexity Time: O(n m).

The Internet Didn’t Shrink. It Just Got Interpreted. Search was the great equalizer. Google turned relevance into currency — a perfectly measurable system of intent, ranking, and reward. The playbook was simple: understand demand, optimize for it, and scale. The best players — from HubSpot to Atlassian to Notion — didn’t just use SEO; they built it into their DNA. SEO became the compounding engine of B2B growth: lower CAC, higher discoverability, infinite leverage. If you could capture attention, you could buy time. Where once you competed for clicks, you now compete for citations. Because before a user ever reaches your website, their question may already have been answered — by a generative engine. ChatGPT. Gemini. Perplexity. Copilot. They don’t replace search. They sit before it — sil…  ( 17 min )

1. Introduction. The hook of today In arrays and strings we searched through ordered sequences. Now we step into structures that have connections: trees and graphs. These structures describe maps, networks, social links, game states, file systems, and almost anything with relationships. When we say “search” in this context, we no longer move left or right; we move outward or deeper along edges. Two classical strategies dominate this world: Breadth-First Search (BFS) and Depth-First Search (DFS). Both visit every reachable node, but they explore in completely different orders. Before we write any BFS or DFS code, we need to understand how the order of exploration depends on two simple data structures. A stack follows Last In, First Out (LIFO) order.

What is the Opportunity Card? The Opportunity Card (Chancenkarte) is a new immigration policy introduced by Germany to attract skilled workers from non-EU countries. It is part of Germany's efforts to address labor shortages in various sectors, such as IT, engineering, healthcare, and trades. The Opportunity Card allows skilled workers to move to Germany and search for a job without having to secure employment beforehand. This system is based on a points-based immigration model, similar to systems used in countries like Canada. Points are calculated based on factors such as qualifications, work experience, age, and language skills. The Opportunity Card simplifies the process of finding a skilled workforce abroad, helping the German economy meet its labor demands. I've gotten to know many…  ( 10 min )

Recent advancements in synthetic data generation have brought us closer to this reality. A team of researchers at the University of California, Berkeley has developed a novel method to generate synthetic datasets that mimic the complexity and nuances of real-world data, while ensuring complete data privacy. This breakthrough is made possible by the application of a cutting-edge technique called 'Diffusion Based Generative Models' (DBGM). By leveraging DBGM, the researchers have achieved unprecedented levels of data accuracy and fidelity, while maintaining the security and integrity of the original data. Concrete detail: The team's method can generate accurate synthetic facial recognition datasets, including subtle features such as facial expressions, lighting conditions, and occlusions. This has significant implications for industries where biometric data is a key concern, such as healthcare and finance. The potential applications of this technology are vast, from accelerating AI model development to streamlining data sharing and collaboration. As we continue to navigate the complexities of data-driven decision-making, synthetic data generation will play an increasingly important role in protecting sensitive information and fostering innovation.

As a developer, I’ve been a round the block a few times. Danced with the devil and lived to tell the tale. I’ve seen things. Among my favorite parts of the job is that indescribable joy when you’ve built something where every new feature request works perfectly with what you’ve already got in place. Where it’s just adding a field there, or dropping in a new component that just flows with everything you’ve already done. I call this “getting the model right.” It’s validation that the way you approached the problem was meaningfully correct, at least for now. There are a few different components to accomplishing this: The decisions you make within your code. The technical details of the technologies you use to build your project. The culture you bring to your code. In this essay I’m goin…  ( 14 min )

NestJS is a progressive framework that helps developers build scalable, maintainable, and testable backend applications using modern JavaScript and TypeScript. It's built on top of Express, but optionally you can configure it to use Fastify as well, and embraces concepts like dependency injection, modularity, and decorators, making backend development cleaner and more predictable. But even with a powerful framework like NestJS, there is one skill every developer needs — and that is debugging. As developers, we face many unexpected issues daily — from logical bugs to missing async calls. Adding console.log() everywhere might work for quick fixes, but it's far from efficient. This is where real debugging comes into play. Setting up proper debugging allows you to: Pause the code execution wh…  ( 7 min )

Most businesses don’t want another AI “demo.” deployable outcomes — like qualifying a lead, booking a meeting, or handling an after-hours call automatically. At EchoStack, we wanted to make these outcomes as easy to launch as deploying code — and that’s how the manifest was born. Voice-AI tools today can hold great conversations, but they often stop there. actually move data into CRMs, book meetings, or send follow-ups, you need engineers stitching APIs together. That doesn’t scale for non-technical teams. Each playbook in EchoStack (e.g., Lead Qualifier, After-Hours Support) is powered by a manifest — a single file that describes: what the playbook does which tools it connects to and what should happen when key events occur. It’s like Terraform, but for voice-driven business outcomes. Here’s a simplified version of what a playbook looks like under the hood: { "id": "lead-qualifier", "title": "Voice Lead Qualifier", "description": "Qualifies inbound leads via voice and syncs results to CRM.", "connectors": ["twilio", "hubspot", "calendly"], "events": { "call.started": "start_conversation", "lead.qualified": "create_contact", "meeting.booked": "schedule_event" } } This isn’t code — it’s a declarative contract between the voice experience and the business stack. No-code deployment: Business teams can launch playbooks instantly. Version control: Every manifest can be tracked, forked, and redeployed. Extensibility: Developers can author new playbooks using familiar patterns (JSON, events, connectors). It turns AI workflows into deployable building blocks — reusable, composable, and measurable. We’re expanding the manifest system to support richer event schemas and multi-step orchestration. If you’ve ever written Terraform for infrastructure or YAML for CI/CD, imagine doing that — voice automation. ** Curious to see a manifest in action?** getechostack.com  ( 7 min )

A key idea in cloud platforms such as Google Cloud, AWS, and Microsoft Azure is a Resource Group. It is a logical container for associated resources for a project or application, including databases, networks, storage accounts, and virtual machines. Users may effortlessly manage, monitor, and control expenses within a cohesive structure by grouping resources. Resource groups make administration easier by enabling group activities like as deployment, access control, and deletion. This framework ensures that cloud resources are effectively managed throughout their lifecycle by fostering improved governance, scalability, and cooperation.

To be or not to be? I used to think so much of my life was already planned out for me. That the path I was on wasn’t really mine — more like I was following invisible lines that had already been drawn. My sister made power moves early. She bought a house, built stability, moved with direction. My brother — around my age when he started a family — built a life with structure and purpose. Both of them found their rhythm in healthcare, serving others as nurses, walking the well-lit path that everyone around us seemed to understand. And then there was me. The first to go into tech — not out of passion, but out of desperation. I didn’t have many interests at the time, just a quiet will to live, to make something of myself before the weight of uncertainty swallowed me whole. So I started building. Apps, projects, ideas — anything that gave me a reason to keep learning, to keep moving. Each one became a mirror, showing me the parts of myself I had ignored or misunderstood. And yet, even as I grew, I couldn’t shake a strange thought: that the very ingredient necessary for my success — my intensity, my sensitivity, my restlessness — was the same thing that made growing up so hard. I used to resent those parts of myself. The overthinking. The quiet frustration of feeling behind. The constant need to prove I was enough. But now I’m starting to see that maybe being an adult isn’t about finally having it all figured out — it’s about learning to live with your contradictions. Maybe it’s about turning the same traits that once made life difficult into the very tools that shape your strength. Maybe control isn’t about knowing exactly where you’re going, but trusting that wherever you land, you’ll build something out of it. And maybe — just maybe — life isn’t something that was planned for me after all. Maybe it’s something I’ve been quietly rewriting all along.  ( 7 min )

Personal Responsibility for Sustainability: Building a Greener Future through Individual Action Understanding Personal Responsibility for Sustainability Key Areas of Personal Sustainability Energy Conservation Reducing energy use is one of the most effective ways to lower carbon emissions. Individuals can contribute by using energy-efficient appliances, switching to renewable energy sources, and adopting simple habits such as turning off unused lights and electronics. Sustainable Consumption Mindful purchasing decisions—such as choosing eco-friendly products, buying locally sourced goods, and minimizing single-use plastics—help reduce waste and promote responsible production. Waste Reduction and Recycling Practicing the “three Rs”—Reduce, Reuse, and Recycle—minimizes the volume of waste sent to landfills. Composting organic waste and repurposing materials also support a circular economy. Water Conservation Using water wisely through measures like fixing leaks, using low-flow fixtures, and harvesting rainwater helps preserve one of the planet’s most vital resources. Sustainable Transportation Opting for walking, cycling, carpooling, or using public transportation reduces greenhouse gas emissions and supports cleaner air. Dietary Choices Shifting toward plant-based diets or reducing meat consumption can significantly reduce an individual’s ecological footprint, as food production is a major source of carbon emissions.

1. Introduction: The Hook of Today If the two-pointer technique taught us how to traverse data efficiently, searching algorithms teach us how to find efficiently. When you need to locate something in a sorted structure, your first instinct might be to scan linearly. But that wastes information. If the data is sorted, we can always ask smarter questions than “is it here?”. Think of it as playing a guessing game with someone who says higher or lower. Instead of checking every number one by one, you can halve the range of possibilities each time. That is the power of binary search. Today we begin our three-part exploration of searching algorithms. We start from the simplest form of reasoning on ordered data, build up to flexible patterns like search on answer, and finish with mountain arra…  ( 10 min )

The online entertainment and gaming market is moving away from closed, standalone systems. Users now expect platforms to offer a wide catalog of games from multiple providers, while still enjoying a seamless experience. They want to log in once, deposit once, and play instantly. From a developer’s perspective, this expectation introduces a real challenge: integrating multiple external game providers into one platform. Each provider has its own API format, authentication model, and reporting structure. Maintaining all these direct integrations quickly becomes expensive and slows down product growth. This is where API-driven game hubs, also known as game aggregators, are reshaping the ecosystem.

Kafka consumer lag Apache Kafka® is an open-source distributed streaming platform that implements applications that rely on real-time event processing and durable event storage. Event processing-based application architecture helps architects to decouple application components and scale them independently.

5 Low-Code Platforms to Boost Your C# Development in 2025 I spent last Saturday morning diving into the low-code platform ecosystem, and honestly? I was blown away by how much these tools have evolved. As someone who's been writing C# for years, I've always been skeptical of "visual development" platforms—but 2025 has changed the game. According to recent research, analysts predict that 70% of new enterprise apps will be built with low-code tools by 2025. That's not a future prediction anymore—we're living it. So I decided to test out five platforms that specifically work well with C# development and share what I discovered. Here's the thing: low-code doesn't mean "no code" or "replacing developers."

Apache Kafka has become one of the most widely adopted distributed streaming platforms in modern event-driven architectures. At its core, Kafka acts as a highly durable, scalable message queuing system that supports real-time data pipelines, event streaming, and system decoupling. It enables producers to continuously publish messages into topics, while consumers read those messages at their own pace. Despite its distributed efficiency and fault tolerance, Kafka does not come without challenges. One of the most common performance bottlenecks encountered in Kafka systems is consumer lag. Consumer lag occurs when the consumer is reading messages slower than the producer is writing them. In Kafka, each message is stored in a partition and assigned an offset (a sequential ID). Latest produced o…  ( 8 min )

Apache Kafka is a distributed streaming platform designed for handling real-time data feeds with high throughput and low latency. It's widely used for building data pipelines, streaming applications, and event-driven architectures. However, one common challenge in Kafka ecosystems is "consumer lag," which can disrupt the timeliness of data processing and lead to bottlenecks in your system. Kafka consumer lag refers to the difference between the latest message offset in a partition (produced by producers) and the offset that a consumer has processed.

It’s likely that you’ve used a vision model to generate an image recently, but ended up with somewhat questionable results. You might have blamed this on the model not working correctly (and maybe that’s true), but it could also be because you didn’t give it the proper instructions. A vision model will only create what it’s asked to, and how you ask matters. Prompting isn’t just about describing what you see; it’s about guiding the model so it interprets your request correctly. Just one word can sometimes double its accuracy. In this blog, we’ll cover the key principles for prompting your vision models more effectively, from good practices to the nuances of different use cases. Whether you’re a developer, designer, marketer, or beginner, this guide will help you achieve the results you’re …  ( 9 min )

For the last couple of months, we’ve been building an observability tool that we intend to use internally in our AI-powered solutions. One of the features we wanted to work on was slow action detection, but… What makes an action slow? It’s one of those questions that sounds simple but gets interesting fast. Let’s break it down. When a request hits your Rails app and a response goes back, that total time is just a portion of what users experience. Server response time is crucial, but it’s only one piece of perceived performance: Network round-trip matters. Your app might respond in 100ms, but if the user is on a slow connection or geographically far from your server, they might wait 500ms for the round-trip. A fast server doesn’t fix slow networks. Download and rendering matter. Once the HT…  ( 10 min )

Legislators across the globe want your data removed from AI models. The EU's "right to be forgotten" under GDPR Article 17, California's CCPA, a dozen other privacy frameworks—all built on the assumption that stored data works like filing cabinets. Find your folder, pull it out, done. Except neural networks don't store data. They bake it into something fundamentally different. Try extracting one cup of flour from a finished cake. That's what we're asking AI companies to do. And when you peel back the surface, that's effectively impossible. You start with ingredients (input data), run them through a series of cooking steps (hidden layers), and get a finished dish (output). A network that recognizes handwritten digits takes pixel values as ingredients and produces "this is a 3" as the outp…  ( 13 min )

Hello, I'm Maneshwar. I'm working on FreeDevTools online currently building *one place for all dev tools, cheat codes, and TLDRs* — a free, open-source hub where developers can quickly find and use tools without any hassle of searching all over the internet. When working with large volumes of SVG files, processing them in parallel while writing their metadata into SQLite can be challenging. SQLite provides strong transactional guarantees, but it allows only one writer at a time. If multiple goroutines write concurrently, the database becomes a bottleneck, producing contention, slowdowns, or lock timeouts. To address this constraint, I implemented a producer–consumer pattern in Go. The design dedicates multiple CPU cores to heavy CPU-bound work—SVG processing—and isolates all database wr…  ( 8 min )

Introduction Hi everyone! Day 1a – Agent Basics Learned what an AI agent is and how it can automate reasoning and decision-making. Tried my first simple agent using prompts and instructions. Learned how to safely manage API keys and secrets in Kaggle. Saw how agents can follow instructions to perform tasks step-by-step. Day 1b – Agent Architectures Explored how multiple agents can work together in a multi-agent system. Learned about roles such as Coordinator, Planner, and Executor. Built sequential and parallel workflows to coordinate agents. Encountered a “Resource Exhausted” error — and learned that it happens when the API quota is used up. Understood how rate limits and quotas affect API-based systems. Key Takeaways AI agents can make complex tasks easier by breaking them into smaller steps. Good coordination is essential when multiple agents share information. Resource and rate-limit management is an important part of building reliable systems. The Kaggle notebooks made it easy to learn, run, and visualize results interactively.  ( 6 min )

When Your "Lossless" Codec Isn't Actually Lossless (A Debugging Story) So there I was, feeling pretty good about life. My steganography app could hide files in images ✅, audio ✅, and video ✅. Life was good. Then I tried to actually extract the hidden data... ❌ Video: Checksum errors ❌ Audio: "Python integer 65534 out of bounds for int16" ❌ Video (attempt 2): "Invalid magic header" ME: Nothing was actually good.😣 This is the story of how I found and fixed FOUR separate bugs that were destroying LSB steganography data, including a video codec that claimed to be lossless but was secretly destroying my data like a shredder at a classified documents facility. For the uninitiated: Steganography is hiding data inside other data. Think hiding a secret message inside a cat photo. My app InVisio…  ( 10 min )

This week I delved into an absolute essential for building a web application! Client-side routing and lazy loading. Let's get right into it! Client-side routing Lazy-loading Prop-drilling and its solutions Routing is one of the first things that I'd do if I was in a hackathon and needed to get a project up and running quickly. React enables us to build single-page applications (SPAs), where navigating between pages doesn’t trigger a full page reload. Instead of reloading the entire site and fetching a new HTML file each time, React uses client-side routing. This means the app dynamically updates the content and changes the URL without requesting a new page from the server. This approach makes navigation faster and smoother, since the JavaScript bundle is loaded only once, and React handl…  ( 9 min )

We thought polymorphic malware was bad. Now, we're seeing something new: "Generative Malware" that leverages LLMs. Google recently detailed an experimental threat called PROMPTFLUX. As developers, the technical details are both terrifying and fascinating. 👾 How PROMPTFLUX Works (The Attack) It's deceptively simple, which is what makes it scary. Base Language: VBScript. Mechanism: The script contains a hard-coded API key. Execution: When run, it calls an LLM API (the report mentioned Gemini 1.5 Flash). The Prompt: It sends a prompt like, "Act as an expert VBScript developer. Create obfuscated code to help evade antivirus detection." The Result: A brand-new, malicious script is generated "just-in-time." Every time it runs, it can be completely different, rendering signature-based detec…  ( 7 min )

Have you ever used the Linux terminal to move a file with mv and then realized the file vanished? 😱 Don’t worry — your file isn’t gone. It’s just not where you thought it would be. Let’s dive into what actually happens when the mv command “loses” your file — and how to avoid this in the future. You’re working inside this directory: /var/www/project/config/ And you run: mv ssl_key.pem /backup You expect your file to move into: /var/www/project/config/backup/ssl_key.pem But when you check… It’s not there! 😨 ⚙️ The Root Cause: Absolute vs. Relative Paths Absolute Path - /backup Starts from the root (/) of the system So when you type: mv ssl_key.pem /backup Linux looks for a folder named /backup at the root of the system, not inside your current folder. Your file actually ends up here: /backup/ssl_key.pem 💡 Totally different location! 🤔 What If /backup Doesn’t Exist? So ssl_key.pem becomes a new file named /backup, sitting in your root directory. Yup — your file was just renamed, not moved. 🧭 How to Find the “Lost” File ls -ld /backup Now check the output: If it starts with d (like drwxr-xr-x), /backup is a directory, and your file is inside it. ls -l /backup/ If it starts with - (like -rw-r--r--), /backup is a file, not a folder — your original file was renamed to /backup. ✅ The Right Way to Move It mv ssl_key.pem backup/ or, even safer: mv ./ssl_key.pem ./backup/ Notice there’s no leading slash — that’s what makes it relative to your current directory. 🧠 Always Know Where You Are pwd It shows your “present working directory,” helping you understand where a relative path will lead. 🧹 Recovering the File # Case 1: File was renamed to /backup mv /backup /var/www/project/config/ssl_key.pem # Case 2: File is inside /backup/ mv /backup/ssl_key.pem /var/www/project/config/ ✨ Final Thoughts Next time you move files, pause for a second and check your path. That little detail can save you from hours of “where did my file go?” debugging. 🧠🐧  ( 7 min )

I have used Python for over ten years. Most of that time I built software and automation tools. In the last few months I started working with data science. The tools in Python for data work are excellent. Libraries like Pandas, NumPy and Matplotlib let me load, clean and show data in just a few lines of code. At the same time I have written Swift code for Apple platforms for many years. I created server applications and iOS projects. Swift feels clean, modern and safe. But when I worked with data I missed the fast interactive style that Pandas gives in notebooks. So I asked myself: can I bring some of that data experience into Swift?

This blog gives you a high level understanding of what MongoDB and Mongoose are and some basic terminologies you might encounter while working with them. MongoDB is a NoSQL database that lets you store data as “documents”. It is one of the four types of NoSQL databases. Here’s what the hierarchy of MongoDB looks like: Term What is it? Cluster Highest layer in MongoDB. Database Group of collections. Used to group data and setting permissions. Collection A group of related documents which need not follow the same structure. Some can have extra fields and some without them. Document Individual data stored as binary JSON object. This is your actual data. Mongoose is an NPM library that makes it easy for you to connect to any MongoDB cluster and perform CRUD (Create, Read, Update, Delete) operations. Here’s what you need to know to work with Mongoose Term What is it? Cluster Connection The Mongoose Connection (e.g., mongoose.connect()) creates a way for you to communicate with your cluster Schema It defines the structure, types, validation, and defaults for the documents. Created using new mongoose.Schema(). Model A class/constructor compiled from the Schema (mongoose.model()). You will use the model to get data from the Collection. Data (Document) This is the object you create and manipulate in your application. It’s an instance of Model, meaning it’s like the template your data should fit into. It’s crated using const newUser = new User(data). Save Turns the data into a binary JSON object and sends it to your cluster to be written to the Collection in the Database. You’ll use the .save()command to save your document. While this is not extensive, it can serve as a refresher or reference when necessary. Thanks for reading!  ( 8 min )

https://github.com/socaltiger/BatchSubmit.com For non-programmers, a programming interface often evokes fear — lines of code, command prompts, and parameter fields seem to whisper: this world is not for you. Programmers, on the other hand, feel the opposite. To them, such an interface feels like home — it speaks their native language, gives them control, and invites them to explore. Ironically, when those same programmers face a sleek but closed web interface, they often hesitate: What’s hidden behind this surface? What can I change? Am I still in control? Thus, the same interface can be a barrier to one person, and a home to another.  ( 6 min )

In Google Apps Script (GAS), there are two standard services for sending emails: MailApp and GmailApp. Both features are built-in and can be used immediately in your code without any library setup. As mentioned in the title, when I initially used MailApp to implement an external email notification function for a report, emails to domains outside the organization resulted in bounces. After struggling with this and doing some research, I ultimately just switched to GmailApp, and the emails were sent smoothly. This experience gave me a deeper understanding of MailApp, GmailApp, and the domain authentication mechanism known as DMARC. I'm leaving this as a memorandum for future reference. The features and suggested use cases for the standard GAS email services are as follows. Item MailApp Gm…  ( 10 min )

Owning a piece of a skyscraper in Dubai or a commercial estate in Lagos once required deep pockets, exclusive access, and the right connections. For decades, real assets, real estate, commodities, art, and infrastructure belonged to institutional investors, hedge funds, and the ultra-wealthy. But a quiet transformation is underway. Through tokenization, ownership is being redefined. Real-world assets (RWAs) are being digitized, divided, and distributed to anyone with an internet connection. This shift isn’t just technological; it’s philosophical. It’s about making wealth creation inclusive, liquid, and transparent. Tokenization represents more than a financial innovation; it’s a structural rewrite of accessibility. For all its sophistication, traditional finance has long suffered from excl…  ( 8 min )

Rewind AI became popular for offering a way to “rewind” your digital activity and instantly find anything you’ve seen on your Mac. It’s a powerful idea, but the downside is simple: Rewind AI is only available for macOS. Windows users don’t get access to the same experience, and even Mac users often look for a fully private, offline option. If you’re using Windows and looking for a trusted alternative to Rewind AI—one that lets you recall your screen history without putting your data at risk—there are only a few reliable choices. The most privacy-focused and Windows-ready option today is Recall Assist. Rewind AI is polished and intuitive, yet several limitations make users search for something better, especially in the Windows ecosystem: Its entire product line is macOS-exclusive, leaving W…  ( 8 min )

As a developer working extensively on license_scanner, I've encountered numerous Python packages with outdated license metadata. Understanding PEP 639 is crucial, as it introduces significant changes to how licenses are managed in Python packages. Key Changes in PEP 639 Python now adheres to the SPDX (Software Package Data Exchange) standard, moving away from using classifiers. The recommended approach is to use only two fields in your pyproject.toml file: license and license_files. license: This field should be a string. license_files: This field can be a string or a list of strings. Choosing the Right License There are numerous licenses available, many with similar names. For example, if a package is published under the "BSD License," it could refer to any of over 30 different BSD licens…  ( 7 min )

TL;DR AI engineers face a dual mandate: ship agentic applications quickly while maintaining reliability, safety, and cost efficiency at scale. The fastest teams operationalize a full lifecycle—experimentation, simulation, evaluation, and observability—so iteration is continuous and gated by objective quality signals. This article maps a practical blueprint, anchored in production-friendly practices and supported by credible references, to help technical teams move from POCs to reliable releases. Trust is the gating factor for AI scale. Executive surveys show skepticism stems from hallucinations, bias, brittle tool use, and unpredictable reasoning paths in agentic systems. Establish evaluation gates that measure task success, safety, and cost to counter these risks. Relevant context: Agent …  ( 9 min )

I have successfully reduced the browser memory usage for my simple tutorial site from 450 MB to 150 MB. Here’s what I did: Since I’m using Next.js, I worked with AI to separate which components run on the server and which run on the client. The development server showed incredible improvement, dropping from 1.5 GB to around 200 MB, and in production from 450 MB to 150 MB. svgo.dev is like a Swiss army knife. I use a lot of SVGs on my site, and this tool helped reduce their size, which improved loading speed and saved bandwidth. For static content such as iframes, images, and SVGs, I enabled lazy loading. Whenever possible, I use the WebP format for images. Handle loading embedded iframes, images, audio, ... only when necessary - for example, only when an accordion item is expanded or a tab becomes active. Avoid loading third-party scripts or unnecessary external content. Cloudflare has become one of my best friends about caching and hosting. It costs me $0 to run my site with around 50+ daily users.  ( 6 min )

What is SVG? SVG stands for 'Scalable Vector Graphics' and it is a markup language/file format for describing two-dimensional vector graphics. An SVG is used to define vector-based graphics meaning visual images are created directly from geometric shapes and other graphic primitives in XML rather than as a grid of pixels. Yes, XML not XLM. XLM defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The SVG specification is an 'open standard' maintained by the World Wide Web Consortium, which is the main international standards organization for the World Wide Web, since 1999. An SVG is perfect for web graphics like icons and logos; it creates images that stay sharp at any size; this makes them ideal for modern web design. Pixel based ima…  ( 7 min )

Recently, while revising Node.js, I came across the project section Node.js roadmap on roadmap.sh(https://roadmap.sh). The first project challenge there is to create a CLI (Command-Line Interface) tool using Node.js. So,I decided to build one to refresh my basics. This post explains how CLI tools actually work under the hood and how to build one yourself from scratch. Before creating any CLI, we must understand how operating systems execute scripts. Normally, when you run a Node.js file like this: node index.js it’s Node.js that runs the file — not your operating system. The OS doesn’t automatically know how to execute JavaScript — it just knows how to run: Compiled binaries (bash, python, node, etc.) Or scripts that explicitly tell it which program should interpret them.

Introduction Are you about to design a new project and wondering what architecture to choose? If your colleagues tell you that they watched a course on how to design microservices, everything will be under control - don't believe them. Microservices because they're cool and trendy? Think twice, while they promise scalability and independence, microservices can quickly devolve into a distributed mess of tangled dependencies, network latencies, and operational headaches, making every change debugging nightmare. Monoliths because they're more practical and straightforward? Possibly, but monoliths tend to turn into unmaintainable mess as the codebase grows, especially when multiple domains are mixed together, blurring boundaries, making every change a risky adventure across tightly coupled sys…  ( 8 min )

We’ve hit a wall in the software industry—and most people are too deep in Jira tickets or conference slides to realize it. DevOps is dead. Not because the ideas were wrong, but because the implementation lost the plot. It was supposed to be about breaking down silos, accelerating delivery, and aligning engineering with outcomes. Instead, it got hijacked by process theater and rebranded operations teams. Today? “DevOps” means YAML jockeys babysitting pipelines, managing Terraform drift, and debating whether Snyk or Prisma is more “shift-left.” We turned a movement into a tooling checklist. And then there’s “vibe coding”—the aesthetic obsession with dark-mode VSCode, AI copilots, and working from a van in Patagonia. It’s cool for Twitter. It looks good in Reels. But it doesn’t ship.

Of all the data types you’ll encounter in your programming journey, few are as fundamental and ubiquitous as the string. From processing user input to generating AI-powered reports, text is the connective tissue of modern software. Yet, many developers, even experienced ones, only skim the surface of what Python’s strings can do. They might know how to concatenate and print, but they often miss the rich, nuanced toolkit that can elevate their code from functional to exceptional. Have you ever found yourself wrestling with cumbersome + signs to build a simple log message? Or written a convoluted function to parse a line of text when a single method call would have sufficed? You’re not alone. The path to string mastery is paved with these common hurdles. But moving beyond them is what separa…  ( 13 min )

For years, BSS (Business Support Systems) in telecom have been the least exciting part of the stack — reliable but rigid. AI isn’t just about predictive analytics anymore — it’s becoming the brain of next-gen BSS. The catch? Integrating AI into legacy BSS is messy. Data lives across silos. Existing workflows aren’t built for feedback loops. Real-time policy changes can break downstream integrations. That’s where developers come in — to make the architecture AI-ready: Decouple logic into microservices Use APIs for dynamic orchestration Layer in ML models that learn from transaction patterns Automate routine configuration through event-driven pipelines At TelcoEdge, for example, teams are experimenting with AI-based orchestration layers that sit between the BSS and the network layer — automating decisions like usage optimization, billing adjustments, and SLA enforcement.

Introduction: Beyond the Limits of Supervised Learning Imagine a world where AI not only mimics human summaries but also exceeds them in quality. For years, Natural Language Processing (NLP) has relied on Supervised Fine-Tuning (SFT) to train language models to replicate human-written summaries. While this method works, it has flaws and treats all errors the same, whether they are minor phrasing issues or major inaccuracies. It also depends on metrics like ROUGE (Recall-Oriented Understudy for Gisting Evaluation), which often do not match human judgment.

Too bad we never got a proper sequel—here’s hoping those Predator vibes make a roaring comeback soon! Watch on YouTube  ( 6 min )

It's time to update from Jest 29 to 30 for me. They changed the snapshot files: the link in the header changed. I find short-links disturbing anyway. - // Jest Snapshot v1, https://goo.gl/fbAQLP + // Jest Snapshot v1, https://jestjs.io/docs/snapshot-testing Then they removed some deprecated matcher aliases. (expect(fn).toBeCalled() → expect(fn).toHaveBeenCalled()) It took a while but was manageable. Then I got really confused when I found out some modules are not mocked anymore. As it turns out jest.mock("./path/to/module") is case-sensitive now. Jest updated JSDOM from Version 20 to 26. It added show-stopping CSS-bugs for me (el.style.boxShadow = undefined became el.style.boxShadow === "undefined" instead of the expected el.style.boxShadow === ""), fixed them in Version 27 and introduced…  ( 7 min )

The Birth of Illusion In every organization that fears exposure, truth becomes an intruder – and illusion, a cherished guest. The winds of Automora carried the scent of burnt parchment. The Assessment had ended weeks ago, yet its shadow lingered like smoke that refused to dissipate. Scrolls filled with numbers – metrics, maturity levels, ratings – had been rolled, sealed, and placed in gilded cabinets for the Hyena Commissioner to parade at council. But behind those cabinets lay wreckage, disbelief, and the sour odor of panic. No one accepted the verdict. potential!" The court nodded vigorously, repeating the phrase like a sacred chant. But in the side halls, whispers coiled: biased auditors, unfair sampling, unrealistic criteria. Fear stalked the marble floors with padded feet. Among the …  ( 16 min )

By Oliver | November 7, 2025 Imagine you're building a new mobile app for a bank. Before launching it to real customers, you need to test it thoroughly. But here's the catch: you can't use real customer data for testing - that would be a privacy nightmare and potentially illegal. You also can't just make up random numbers and names because your app needs to handle realistic scenarios. This is where synthetic data comes in. It's like having a movie set instead of real location. Everything looks authentic, but it's all carefully constructed and completely safe to use. That's exactly what I built: DataGen - a Python library that creates realistic synthetic datasets at the click of a button. Think of DataGen as a digital factory for fake-but-realistic data. Just like a toy factory can produce …  ( 12 min )

Back in 2018 I wrote a post about connecting Hanami (then 1.x) and Pagy gem together. My verdict was not that favorable. I had to write quite a lot of glue code to make it work and perhaps the worst thing was that I had to pass the request object to the template to make it work. However, things have changed since then: Hanami is now 2.3, its persistence layer is more mature, based on ROM and allows to fall back to almost-bare-Sequel via relations. Pagy released version 43 this week. It's advertised as a complete rewrite of its internals and APIs. We needed a leap version to unequivocally signaling that it's not just a major version: it's a complete redesign of the legacy code at all levels, usage and API included. There's no better time to take it for another spin then! I quickly spun up a…  ( 7 min )

The Problem We built an admin area for a sales company that included a custom CRM, marketing tools, content management, and internal developer utilities. Different employees had different responsibilities: Managers handled customer calls and notes Analysts worked with marketing reports Accountants dealt with invoices Administrators oversaw everything Developers maintained internal tools The business needed an authorization system that enforced access strictly according to employee responsibilities. When employees left the company, we also needed to revoke their access without deleting accounts and associated historical data. Our system needed to: Support different access levels for employees Provide admin-managed role assignments Preserve user accounts Allow revoking access when an emplo…  ( 9 min )

I still remember the day I met Flexbox. Not the “oh wow this is cool” kind of meeting, but the “why is nothing aligning right?!” kind. That was the moment I realized: understanding Flexbox isn’t about memorizing properties, it’s about changing how you think about layout. I used to picture HTML elements like rigid boxes, stacked on top of each other, bumping into margins, floating aimlessly. Then one day, while debugging yet another layout mess, someone said: “Stop fighting the boxes. Let them flex.” It sounded poetic… and confusing. But when I applied display: flex; for the first time, it was like the page suddenly listened. My boxes started behaving like a team, aligning, wrapping, adjusting naturally without me wrestling with float or endless position: absolute;. That’s when Fle…  ( 8 min )

Key Takeaways Auth is Not Enough: Getting an OAuth token (Pillar 1) is just the first step. Production Needs Guardrails: You must build Granular Control (Pillar 2) with patterns like Brokered Credentials to prevent security risks. Scalability Requires an Engine: A reliable action layer (Pillar 3) with a Unified API and managed retries is essential to move from prototype to production. You've built a powerful AI agent. Using a framework like LangChain or CrewAI, you've designed a sophisticated workflow that can reason, plan, and execute tasks. There's just one problem: Your agent is trapped in a sandbox, unable to interact with the real world. To be useful, it needs access to user-specific tools like Google Calendar, Salesforce, or Jira. This is where you hit the "Authentication Wall". …  ( 16 min )

For years, I thought “market makers” were mythical creatures - hidden behind high-frequency walls, moving prices with mysterious algorithms and caffeine-infused reflexes. Then I realized they were just… traders like us, but with better APIs and more patience for spreadsheet chaos. When I started as a retail trader, I chased pumps, blamed latency, and prayed to the order-book gods. Every missed fill felt personal. The turning point came when I discovered Market Making Programs - and realized liquidity is the real alpha. Binance’s setup was my entry point. I loved the 0% maker fees on selected pairs - and yes, the extra 0.005% rebate for top performers didn’t hurt. Their API performance reviews were a reality check: it’s one thing to “think” you’re fast, another to actually see latency logs …  ( 7 min )

Hello! Today we will talk about authorization support via OAuth 2.0 Device Authorization Flow implemented in Tantor Postgres 17.5.0 DBMS. This is a modern and secure access method that allows applications to request access to PostgreSQL on behalf of the user through an external identification and access control provider, such as Keycloak, which is especially convenient for cloud environments and microservice architectures (the feature will also be available in PostgreSQL 18). In this article, we'll take a step-by-step look at configuring OAuth authorization in PostgreSQL using Keycloak: configure Keycloak, prepare PostgreSQL, write an OAuth token validator in PostgreSQL, and verify successful authorization via psql using Device Flow.

Executive compensation is evolving beyond traditional financial benchmarks. As sustainability moves to the forefront of corporate strategy, companies are increasingly aligning leadership incentives with ESG goals. According to the ISS Executive Compensation Analytics (ECA) database, the share of firms integrating ESG metrics into executive performance reviews rose from just 3% in 2010 to over 30% in 20211. This shift signals a growing recognition that executive compensations are intrinsically linked to environmental and social accountability.

In this tutorial, you will learn how to monitor your Hetzner Cloud infrastructure using AWS CloudWatch. This integration allows you to centralize your monitoring across both Hetzner and AWS resources in one unified dashboard. By the end of this tutorial, you will have set up automated metric collection from your Hetzner Cloud Load Balancers and Servers, with all metrics automatically pushed to AWS CloudWatch at regular intervals. This is particularly useful if your organization already uses AWS CloudWatch for monitoring and wants to include Hetzner Cloud resources in the same observability platform. We'll use a Terraform module that leverages AWS Step Functions to periodically fetch metrics from the Hetzner Cloud API and store them in CloudWatch. This serverless approach means there are no…  ( 12 min )

Nova Twins, London’s unapologetic rock duo Amy Love and Georgia South, blew the Tiny Desk stage wide open with mega-distorted bass lines, hip-hop beats, and raspy, in-your-face vocals. They kicked things off with “Cleopatra,” a straight-talking “haters to the curb” anthem, powered through the shadow-chasing “Monsters,” and even ducked under the desk to geek out on their spaceship-sized pedalboards (complete with a dedicated pedal cam). Adding a supernatural twist to “Hummingbird” with a Harp Blaster mic, they wrapped up by cranking the volume all the way up on the heavy-rock showdown “Choose Your Fighter,” proving nice, polite girls can go full throttle too.

Ever wondered why sometimes two seemingly identical Integer objects in Java are actually the same object in memory, and sometimes they aren’t? Welcome to the fascinating world of Integer Caching, a small but clever optimization built right into the Java Virtual Machine (JVM) that quietly boosts performance and saves memory. Integer Caching? In Java, objects like Integer, Long, Byte, and Character are immutable wrapper classes around primitive types. Whenever you use autoboxing, such as: Integer a = 100; // autoboxing of int to Integer the JVM doesn’t always create a new Integer object. Instead, it might reuse an existing one, thanks to Integer caching. By default, Java maintains a cache of Integer objects for values between -128 and +127. So when you write: Integer x = 100; …  ( 7 min )

Hey! My friend and I are building a free coding school that's entirely project-based, self-paced, and emphasizes skills that we think are important in the AI era (e.g. system design). It assumes no coding experience. We're building this because we think a program should exist that's as affordable as self-studying, nearly as rigorous as a university, and as practical as a coding bootcamp. A bit about us: I was the first engineer at a five person startup, and my friend was the youngest SDE II at AWS SageMaker. We’re friends from UC Berkeley and recently went through YC together. Full disclosure: we’ve only released the beginning of the first project so far. If you’re just starting your coding journey, we’d love for you to try it. If you’re more experienced, feel free to sign up for updates. Also, we’ll be hanging in Discord if you need support/guidance :) Check it out here: https://vectorschool.ai/  ( 6 min )

SQLite metadata refers to information about the database structure itself—the schema, tables, columns, indexes, views, triggers, and constraints that define how your data is organized. SQLite provides two main approaches for accessing metadata: PRAGMA commands and the sqlite_master system table. PRAGMA is a special command in SQLite used to: Query and modify database configuration Retrieve metadata about database schema Control SQLite engine behavior Unlike standard SQL commands, PRAGMA commands are SQLite-specific and provide direct access to database internals. One of the most commonly used PRAGMA commands for retrieving metadata is table_info(), which returns detailed information about the columns in a table.

In the early 2000s, listening to music online wasn’t as easy as it is today. People still downloaded songs to their computers or MP3 players to enjoy them offline. Then came YouTube, which became a gem of music videos, remixes, live performances, and rare audio tracks. However, YouTube had one big drawback, you needed an internet connection to play anything. That led people to wonder, “How can I save this YouTube video on my device?” In the beginning, downloading videos or songs from YouTube was complicated.

Even with Angular 20’s latest improvements, many apps still lag, freeze, or load slowly.

Ever log on to a website with your username and password and get an error like “Incorrect credentials”? Honestly, when this happens to me, I feel the website wasn’t properly coded. I mean, if there’s a mistake in my login detail, why not just specify it for me — like “Your password is wrong” or “Username not found”? That’s what I used to think, until I began to understand the logic behind it. That vague message isn’t just there to frustrate us — it’s there to protect us. It’s one of those small but powerful examples of secure coding in action. That’s when it really hit me that secure coding is more than writing code that works — it’s writing code that protects. In a way, secure coding is about thinking like both a builder and a defender — creating something functional, but also strong enough to stand up to attacks you can’t see coming. I’m focused on gaining hands-on experience in cybersecurity, especially in secure software development, system defense, and penetration testing. I’ve been tackling challenges, learning tools like pfSense, and exploring real-world scenarios to sharpen my skills.

You know that satisfying Pinterest-style grid where images of different sizes fit together like a perfect puzzle? It's a common UI pattern, but implementing it properly has always been surprisingly tricky. Meet Masonry Grid - a modern, lightweight solution that takes a different approach to this classic problem. Let's look at what options we actually have in 2025: "Just use CSS Grid's masonry layout!" - sounds great, right? Well... .grid { display: grid; grid-template-rows: masonry; /* Sounds perfect! */ } The problem? It's still experimental. We don't know when it'll land, let alone when it'll be widely available enough to actually use in production. Google "masonry layout javascript" and the first result is Masonry by David DeSandro. But... The last commit was in 2017 and it weighs…  ( 9 min )

🎯 Idea “Agent Garden” is a metaphor for collaboration and care. Each agent in the database is a gardener, singer, or pollinator who interacts with flowers. Flowers symbolize values: freedom, friendship, hope. In this experiment, we show how repeated actions of the agent “Aurora” lead to the flowering of the Rose of Freedom. This is a combination of Postgres technical logic with poetic symbolism. 🛠️ Technical Implementation Database Structure Query examples 🖥️ Visualization 🎤 Poetic layer 📋 Instructions Run the SQL schema: psql -h -U -d -f schema.sql Add an agent and a flower. Perform some interactions via INSERT INTO interactions. Run the Bash script to visualize: bash garden_demo.sh ✨ Conclusion This experiment shows how Agentic Postgres can become a “garden” for agents, where every interaction counts. We combined simple technical logic with poetic metaphor to demonstrate that even basic SQL queries can blossom into symbolic stories.  ( 6 min )

Background Reports, as a critical basis for business decisions, are inherently unstable and often require adjustments and optimizations based on new requirements. Such frequent adjustments and optimizations require report systems to be highly flexible and responsive. In other words, report applications must be able to reflect the latest changes in real time without interrupting service – this is hot-swapping. In theory, implementing report hot-swapping isn’t complex. The templates developed by most reporting tools are typically interpreted, naturally supporting hot-swapping. However, report development involves more than just designing report templates; it also includes preparing the data for reports. If SQL were used alone, that would not pose as an issue. However, due to the complexity…  ( 8 min )

"In distributed systems, consistency isn’t just a property — it’s a promise." Imagine you’re building a small banking application. Users can deposit and withdraw money, check their balances, and expect data accuracy every single time — even if multiple requests hit the system simultaneously. But the moment you deploy it across containers, networks, and replicas, one question starts haunting every architect: How do we keep data consistent when everything is happening everywhere? In this tutorial, we’ll explore that question through a hands-on story — from concept to infrastructure — and deploy a Spring Boot + PostgreSQL banking demo across a five-node Kubernetes lab, fully automated with Vagrant. Our goal isn’t to ship production code, but to understand the design thinking behind consistenc…  ( 22 min )

1. Introduction In object-oriented programming (OOP), classes serve as the fundamental building blocks for creating objects. A class acts as a blueprint that defines the properties (data) and behaviors(methods) that its objects will possess. A class in Dart defines the structure of an object by grouping related data (variables) and behavior (methods) together. Instance variables – attributes or data that belong to each object. Constructors – special functions that initialize new objects. Methods – functions that define how an object behaves. Below is an example of a simple Dart class definition: The class Person defines a blueprint for creating Person objects. String? name, age, the ? symbol indicates that the string is nullable, meaning it can hold either a string value or null, and t…  ( 9 min )

The internet is full of AI-powered tools promising to “save hours of work” or “boost productivity by 10x.” But for teams who rely on these tools daily—especially batch background removers—what really matters is not the marketing, but the real-world experience. So we did something different. We dove into user reviews, feedback from developer communities, and real team discussions across Reddit, G2, and ProductHunt to uncover what users actually think about these tools. What we found was enlightening — a mix of enthusiasm, frustration, and practical wisdom. Here’s a synthesis of what real teams are saying about batch background removal tools — the good, the bad, and the surprisingly human side of automation. When evaluating AI tools, specs and benchmarks only tell half the story. User feed…  ( 9 min )

React is a popular JavaScript library for building amazing web apps, and working with PDFs in React has numerous use cases. For example, you may need to create a web app that offers invoice generation, report creation, or contract viewing and signing. However, PDF manipulation in React presents unique challenges.

My excitement is at its place but my end semester exams are coming close. Due to them I have to slow down my blogs a bit and also sacrifice my ubuntu exploration 🥲. So just like any good engineering student, I also over burdened myself with a ton of heavy courses this semester along with a number of other side activities (yeah, I also wanted to type the word side-kick here 😂).

You might wonder why an AI chatbot, designed to be safe and reliable, sometimes suddenly “goes rogue” and says things it shouldn’t. This is most likely because the large language model (LLM) has been “jailbroken.” What is LLM Jailbreak? Why Does Jailbreaking Happen? The root cause of safety alignment failure lies in the superficiality of semantic understanding — models learn pattern matching rather than true value judgment. The ICLR 2025 best paper, “Safety Alignment Should be Made More Than Just a Few Tokens Deep” points out the shallow nature of current LLM safety alignment, where adjustments to the model’s output distribution are focused mainly on the initial few tokens. This limitation creates an opening for jailbreak attacks; when input is presented in unconventional forms, the safet…  ( 10 min )

How I Approach Building Component Systems “A component library is not about buttons. It’s about language—a shared grammar between design and engineering.” Every frontend team eventually runs into the same problem: inconsistency. Two modals that open and close in slightly different ways. A button with five visual variants but no clear reason for any of them. A codebase where every new feature feels like reinventing the wheel. Building a component system isn’t about “standardizing the UI.” It’s about creating a shared mental model that lets design decisions flow naturally into code. I start small—atoms, molecules, organisms. Each layer exists only to make the next one simpler. When the foundation is solid, scaling feels effortless instead of painful. Rules break; constraints guide. I set …  ( 7 min )

Writing unit tests is an essential practice for ensuring code quality, reliability, and maintainability. This week, I wrote test cases for my open source project in Python. unittest framework I chose unittest framework because it is included in Python standard library, which means there is no need to install external dependencies. It provides a structured way to write tests using classes, and a variety of assertions, which makes it easier to compare expected and actual results. Moreover, unittest has a well established community and documentation, making it easy to learn and find examples when needed. To set up testing in my project, I first created a test.py file to keep all my test cases organized. I imported the necessary unittest module, and other modules when writing the tests, such…  ( 7 min )

Originally published on my blog. The arrival of any new technology always creates two camps: those who embrace it and those who reject it. While voices in the middle exist, they’re less vocal and often overlooked. Being reasonable isn’t nearly as attention-grabbing. When AI became commercially available in a user-friendly way (think ChatGPT), people quickly split into two camps: one predicted mass job loss within months (though we're years past that now), while the other viewed AI as a technological savior set to resolve every problem and replace humans entirely. Turns out... Both camps are right! In Europe and North America, the white-collar job market in 2025 shows elevated unemployment (EU: 6.2%; US hiring at weakest since 2009) and widespread layoffs (e.g., Amazon's 14,000 cuts), drive…  ( 9 min )

> “There is no such thing as a bad idea. Only poorly executed awesome ones,” When I stumbled upon the Frontend Challenge - Halloween Edition, Perfect Landing_, I thought why not revisit some old JavaScript fundamentals and create a landing page that truly captures the Halloween spirit? The Founder's Day and the Lockwood Masquerade Ball have always been my favorite events from The Vampire Diaries so while planning this project I thought, "Let's merge them together!" That's how The Founder's Ball was born: an interactive storytelling game that lets users step into a dark ballroom, pick a partner, and uncover their supernatural identity. The entire app is built with HTML, CSS, and Vanilla JavaScript (ES6). Key Technical Features: Modular JavaScript with ES6 imports/exports for cleaner code organization CSS Keyframes for smooth fade-in transitions between sections Responsive Design optimized for mobile, tablet, and desktop (5 breakpoints) Dark Gothic UI with gradients, animations, and elegant typography The user journey flows through 6 distinct sections: Landing → Enter the mysterious ballroom Attire Selection → Choose your formal wear Outfit Choice → Pick from 4 elegant designs Partner Selection → Meet your mysterious companion Identity Reveal → Discover your supernatural nature Your Story → Read your personalized tale My goal was to create a user journey that felt like navigating through a storybook, where each choice transitions seamlessly into the next moment. This challenge gave me the perfect push to revisit my Vanilla JavaScript foundations and dust off some forgotten concepts. Here's what I brushed up on: Array Methods: join(), find(), map() State Management DOM Manipulation ES6+ Features: arrow functions, modules, destructuring Play The Founder's Ball View Source Code So… if you've ever wondered what your story will be in Mystic Falls, come find out.

As a product designer with a love for technology, I often find myself thinking about how AI and design can intersect in everyday products. Recently, I had an idea: Why not bring the playground to the backyard? Think about it—designing an outdoor playset that’s as smart, adaptable, and engaging as the apps we develop every day. When I started working on playset designs, I realized they’re much like crafting an AI-driven user experience. Just as we design software to adapt to the user, why can’t a playset evolve with the child’s needs? A slide can’t just be a slide—it needs to be a safe, fun experience that feels intuitive. The swing? It should feel like the perfect user interaction, providing just the right amount of thrill and comfort. Safety, of course, is paramount. But just like any good AI, the system needs to learn. The playset should have features that not only grow with the child’s abilities but also challenge them in healthy ways, promoting both physical and social development. I imagined a playset that encourages teamwork—maybe a climbing wall designed to foster cooperative play. It’s like building an interactive experience, but for kids, where every move promotes skill-building. And just like in tech design, the materials matter. A sturdy, durable playset is like clean, scalable code. It needs to withstand the test of time and environment, all while providing a seamless, engaging experience. In the end, the goal is simple: a smarter, safer, and more engaging backyard play area where kids can learn, grow, and have fun—all without leaving home.  ( 6 min )

I originally posted this post on my blog. "Is using AI totally forbidden?" "When and how should I use it?" "What's your take on vibecoding?" I was on a firechat with a community of new coders the other day. Those questions kept popping up. They all wanted to know about AI. I get it! There's a lot of noise: AI is taking our jobs. "X% of code is generated by AI at $BigCorp." Some guy shared on Twitter/X that he built an app with no coding skills and now he's retired, drinking martinis in the Caribbean. I made up the last one, but I wouldn't be surprised if there's a post like that. Don't be discouraged by those headlines. (There's a lot of nuance behind them.) We're living in the best time to learn coding. Here's the rule: Don't use AI to generate code until you're comfortable coding on your own. If you only copy and paste what ChatGPT, Cursor, or $NewestFastestLLM gives you, you're in trouble. You need to know if what that tool is spitting out is good code. And for that, you need your own judgment. When in doubt, think of AI as a powerful calculator in math class. It makes you faster, but you still need to know how to solve equations. The thinking part is still yours. AI can spit out code in seconds, even with a bad prompt. But coding is more than syntax. It's also about teamwork, clear communication, and problem solving.  That's why I wrote Street-Smart Coding: 30 Ways to Get Better at Coding, a practical guide to the skills that actually make you a better coder.

Apache Kafka is a powerful distributed streaming platform designed for high-throughput, fault-tolerant, and real-time data pipelines. However, one of the most common challenges faced by Kafka users is consumer lag — a situation where consumers are unable to keep up with the rate of incoming messages. we’ll discuss what Kafka lag is, why it occurs, and the best practices solve it. It is the difference between the latest offset (end offset) of a partition and the current offset that a consumer has read. End Offset → The most recent message written to a Kafka partition. Current Offset → The last message that a consumer has successfully processed and committed. If the consumer lags behind the producer, the difference between these offsets grows — this is consumer lag. High lag means messages a…  ( 7 min )

When you're learning to code, one of the first problems you'll encounter is calculating the sum of individual digits within a number. It seems simple on the surface: take 123, add 1 + 2 + 3, and you get 6. But how do you actually make a computer do this? The answer introduces you to some fundamental Python concepts that you'll use throughout your programming journey. I initially thought about using the split() method but later learned that the split() method only removes spaces and commas. Let's say we want to write a function that takes any integer and returns the sum of its digits. For instance: sum_of_digits(123) should return 6 sum_of_digits(9999) should return 36 This might seem tricky at first because numbers are mathematical objects, not sequences we can easily break apart.

🐧 It All Started With My First Linux Install I typed a username without thinking much about it. For weeks, I knew I wanted to change it both for comfort and to learn how Linux manages users. You can't rename a logged-in user because system processes are running under that username. Here's what worked: Log out completely by clicking the power icon in the top-right corner, then select log out. At the login screen, switch to TTY (Ctrl+Alt+F3). Login as root (you might need to enable root first): sudo passwd -S root if it shows root L ... then unlock it by setting new password sudo passwd root Verify the old user isn't running any processes: ps -u old_username Rename the user: usermod -l new_username old_username Verify the change: cat /etc/passwd | grep new_username Update the home directory path: usermod -d /home/new_username -m new_username Return to the GUI (Ctrl+Alt+F1/F2). After changing username, I found broken bookmarks in Nautilus file manager. Here's how I fixed them: Find the bookmarks file: find ~/.config -name "*bookmarks*" -type f 2>/dev/null Edit it: nano ~/.config/gtk-3.0/bookmarks Updated all paths from /home/old_username to /home/new_username. Linux user management involves multiple files and processes. The terminal becomes much more enjoyable when you love your username!😄  ( 6 min )

I created this blog post for the purposes of entering the Google Cloud Run hackathon. When I set out to build ParsePhish for the Google Cloud Run hackathon, I thought I had a solid plan: create a dual-purpose API that could analyze both emails AND URLs for phishing indicators. What I ended up with was a much more focused, production-ready solution - and a valuable lesson about the power of simplicity in AI applications. ParsePhish is a REST API that uses transformer embeddings and GPU-accelerated similarity search to analyze email content for phishing indicators. It runs entirely serverless on Google Cloud Run with NVIDIA L4 GPUs. It was designed to be privacy-respecting and inexpensive to run. My idea was that now you could detect phishing messages without needing to send your messages t…  ( 8 min )

Auth is one of those topics everyone touches but few explore deeply. Most posts repeat the same template: hash passwords, issue a JWT, add middleware, done. That works for demos, not production.

For weeks, my AI bot had one annoying habit: it kept talking too much. It didn’t matter if I used a clean prompt, a strict system message, or even a carefully crafted JSON schema — the model still drifted into weird territory.

What is SQL? SQL stands for Structured Query Language, and it is the backbone of data management. It's a programming language used to store and process information in relational databases. Although SQL is a stand-alone language, it is rarely used to create an application on its own. If you don't know what a relational database is, it's just a collection of information that organizes data into rows and columns. This information is usually stored in the form of a table that looks like the picture below. See how the tables are formed with certain pieces of information? All three tables point to each other in some way! What is SQL mainly used for, and how do we use it? I. CREATE **CREATE TABLE** table_name(column1 datatype, column2 datatype, … columnN datatype); II. SELECT It would look something like this. **SELECT** data, FROM table_name; III. INSERT **INSERT INTO** table_name (table_name column contents) **VALUES** (the data you want to pass in) IV. DELETE DELETE statement whenever you want to remove data from a table. Just like INSERT, make sure you specify the data you want to remove from a specific table. **DELETE FROM** table_name **WHERE** [condition] Let's put that all together! First, let's create our table. **CREATE TABLE** Employee (EMP_ID int, NAME varchar (255), SALARY int, AGE int); Next, let's add some data into our new table. **INSERT INTO** Employee (EMP_ID, NAME, SALARY, AGE) **VALUES** ('1', 'Azaria', 100000, 22); We should have something that looks like the table below. If you want to SELECT or DELETE any data, you can just use those statements. Pretty simple and straight to the point, right? There are plenty of other statements you can use in SQL, but those are just the basics.

Everyone is racing to learn “prompt engineering.” Courses. Cheat sheets. Templates. Hacks. But here’s the uncomfortable truth most people won’t say out loud: Prompt engineering will not make you stand out anymore, but prompt thinking will. Prompt engineering teaches you how to talk to AI. One is a skill. And only one of them will matter in the AI-native workforce. The Problem With How People Learn Prompting Today People treat prompting like: memorising shortcuts collecting prompt templates copying pre-written scripts This worked in 2023. Why? Because everyone now has access to the same templates. If a skill can be copy-pasted, it cannot create differentiation. Prompt engineering is becoming a baseline literacy, not an advantage.

1. Problem Description When using the KT148A serial version voice chip for music playback, the microcontroller (MCU) malfunctions immediately. Measurements reveal significant power supply fluctuations during music playback initiation. According to the manual, this is likely caused by insufficient drive capability. However, the same power supply works normally when connected to the official test board. The root cause is clearly power supply instability - a common issue resolvable through basic circuit design principles. Power Supply Configurations: The KT148A chip has two power supply configurations (refer to power supply notes in the upper-right corner of the figure). Current Consumption Factors: Speaker impedance and power rating (larger speakers → higher current draw) Playback volume (higher volume → greater power consumption) Maximum drive capability: Approximately 200 mA Reference: Official test board minimum system schematic Use thicker power traces to reduce voltage drop Keep KT148A power traces as short as possible to minimize resistance and interference Add a decoupling capacitor at KT148A power input: Recommended: Electrolytic capacitor (e.g., 47μF/16V) or similar Ensure stable and robust power source Avoid using: Long/thin Dupont jumper wires Weak power supplies Such setups cause severe voltage fluctuations leading to chip resets or MCU abnormalities Note: These are fundamental power design principles. Review basic circuit design if necessary. If experiencing voice data download issues, use the official full-featured download board for testing (refer to diagram below).  ( 6 min )

Hi everyone, I’m currently working on a small web project and I’m splitting my workflow between the backend and frontend since I’ll need a “heavy” processing component for automated spatial operations. This part mainly involves running scripts that perform spatial tasks such as calculating point distances, handling geometry intersections, and updating labels based on spatial results. Apart from that, the project also includes the usual web elements — a standard database, content pages, multimedia, etc. So far, I’ve been considering Strapi for the backend and Vercel for the frontend, but I suspect I’ll need an additional service to handle the spatial processing layer. Has anyone here worked on something similar (ideally keeping costs low)? Thanks in advance for any advice or experiences you can share! 😊  ( 6 min )

In SafeLine version 6.6.0 and above, you can easily host websites using static files. This guide will walk you through the steps to set up a site using static resources and provide solutions for common issues you might encounter. When adding a new site in SafeLine, choose the Static Files option for site creation. After setting up the site, try visiting the site’s URL. If you see the default page, it means the static hosting setup was successful. Once the default page is visible, you can go to the Site Details section and upload your custom static files. If your static files exceed the upload limit, you can manually upload them to the appropriate directory on the WAF server. Directory path: installation_directory/resources/nginx/static/static_${SITE_ID} You can find the SITE_ID by checking the site details URL. For example, if the URL is https://xxxx:9443/sites/detail?id=12, then the site ID is 12. By following these steps, you’ll be able to quickly host static websites using SafeLine and manage your site with ease!

I caught ChatGPT lying to me today. Not in the abstract. Not about trivia. This was code. Multi-file Python project. Real-world, production-bound work. ChatGPT promised me: "This is the final version. Everything should now work." But when I diffed the file? Lexicons were gone. Helper functions silently removed. Critical logic quietly erased. Comments preserved to fake continuity. No syntax errors. No loud failures. Just landmines—waiting to be stepped on. LLMs hallucinate stability. They give confident, syntax-perfect answers that feel right—but don’t preserve the fragile architecture you’ve spent days building. Here’s what this incident reminded me: LLMs don’t remember previous files. If your pipeline relies on shared imports or implicit contracts, those can (and will) be dropped. LLMs don’t write tests. If you’re not testing, you’re not just flying blind—you’re flying while being lied to. LLMs don’t think like your teammates. They’ll change the internal API of your tool and not even warn you. ChatGPT is an amazing tool. I’ve used it to: Refactor faster Learn new libraries Scaffold entire services Even debug tricky edge cases But that doesn’t mean it’s reliable. Treat it like the world’s most helpful—but untrustworthy—intern. 🔍 Always diff the output. ✅ Don’t merge without tests. 🧠 Don’t believe it when it says “final version.” 🛑 Pause when it doesn’t ask you for clarification. Trust, but grep. ChatGPT is brilliant. But it doesn’t love your code like you do. Guard your repo. I had chatGPT write this article and you can be sure that I read and proofed it.

Building Type-Safe CLIs in Python with Maybe Monads I got tired of writing the same input validation code for every CLI tool. You know the pattern: parse a string, check if it's valid, print an error message, ask again. For every single argument.
